Definition and implementation of a SAML-XACML profile for authorization interoperability across grid middleware in OSG and EGEE  

SciTech Connect

In order to ensure interoperability between middleware and authorization infrastructures used in the Open Science Grid (OSG) and the Enabling Grids for E-sciencE (EGEE) projects, an Authorization Interoperability activity was initiated in 2006. The interoperability goal was met in two phases: first, agreeing on a common authorization query interface and protocol with an associated profile that ensures standardized use of attributes and obligations; and second, implementing, testing, and deploying, on OSG and EGEE, middleware that supports the interoperability protocol and profile. The activity has involved people from OSG, EGEE, the Globus Toolkit project, and the Condor project. This paper presents a summary of the agreed-upon protocol, profile and the software components involved.

Toward SVOPME, a Scalable Virtual Organization Privileges Management Environment  

NASA Astrophysics Data System (ADS)

Grids enable uniform access to resources by implementing standard interfaces to resource gateways. In the Open Science Grid (OSG), privileges are granted on the basis of the user's membership to a Virtual Organization (VO). However, user privilege definitions and enforcements are administered separately by VOs and Grid sites. Such partitioning can potentially introduce inconsistent user privileges throughout the Grid and break the Grid paradigm of uniform access to resources. There is a need for an automated privilege management mechanism for a VO to codify privilege policies granted to its users, to propagate the policies to grid sites, to identity and suggest remedies for non-supported VO privileges at individual sites. The Scalable Virtual Organization Privileges Management Environment (SVOPME) addresses the challenge under the context of the Open Science Grid (OSG). The SVOPME provides tools for VOs to define and publish desired privileges. At a site, SVOPME tools help analyze access policies defined for VO users and verify policy consistency between VOs and sites, and suggest site configurations changes. This paper presents the designs and features of SVOPME tools and the lessons learned in applying SVOPME tools for OSG VOs and sites. Furthermore, we will outline future improvements to SVOPME tools to adapt to a range of different site configurations and new privilege policies.

Adoption of a SAML-XACML Profile for Authorization Interoperability across Grid Middleware in OSG and EGEE  

NASA Astrophysics Data System (ADS)

The Authorization Interoperability activity was initiated in 2006 to foster interoperability between middleware and authorization infrastructures deployed in the Open Science Grid (OSG) and the Enabling Grids for E-sciencE (EGEE) projects. This activity delivered a common authorization protocol and a set of libraries that implement that protocol. In addition, a set of the most common Grid gateways, or Policy Enforcement Points (Globus Toolkit v4 Gatekeeper, GridFTP, dCache, etc.) and site authorization services, or Policy Decision Points (LCAS/LCMAPS, SCAS, GUMS, etc.) have been integrated with these libraries. At this time, various software providers, including the Globus Toolkit v5, BeStMan, and the Site AuthoriZation service (SAZ), are integrating the authorization interoperability protocol with their products. In addition, as more and more software supports the same protocol, the community is converging on LCMAPS as a common module for identity attribute parsing and authorization call-out. This paper presents this effort, discusses the status of adoption of the common protocol and projects the community work on authorization in the near future.

SVOPME: A scalable virtual organization privileges management environment  

SciTech Connect

Grids enable uniform access to resources by implementing standard interfaces to resource gateways. In the Open Science Grid (OSG), privileges are granted on the basis of the user's membership to a Virtual Organization (VO). However, Grid sites are solely responsible to determine and control access privileges to resources using users identity and personal attributes, which are available through Grid credentials. While this guarantees full control on access rights to the sites, it makes VO privileges heterogeneous throughout the Grid and hardly fits with the Grid paradigm of uniform access to resources. To address these challenges, we are developing the Scalable Virtual Organization Privileges Management Environment (SVOPME), which provides tools for VOs to define and publish desired privileges and assists sites to provide the appropriate access policies. Moreover, SVOPME provides tools for Grid sites to analyze site access policies for various resources, verify compliance with preferred VO policies, and generate directives for site administrators on how the local access policies can be amended to achieve such compliance without taking control of local configurations away from site administrators. This paper discusses what access policies are of interest to the OSG community and how SVOPME implements privilege management for OSG.

Federation of TeraGrid, EGEE and OSG infrastructures through a metascheduler

Since its conception, Grid technology concerned itself with interoperability between heterogeneous computers by providing a middleware layer to abstract underlying resource characteristics. Unfortunately there is no agreement today on a common set of standards and, therefore, different conceptions lead to different middleware implementations. That effectively rendered interoperability between grid infrastructures to be a complex issue, from which originally sprang the

Privilege management infrastructure for virtual organizations in healthcare grids.  

PubMed

This paper is focused on the management of virtual organizations (VO) inside healthcare environments where grid technology is used as middleware for a healthcare services-oriented architecture (HSOA). Some of the main tasks considered for the provision of an efficient VO management are management of users, assignation of roles to users, assignation of privileges to roles, and definition of resources access policies. These tasks are extremely close to privilege management infrastructures (PMI), so we face VO management services as part of the PMI supporting access control to healthcare resources inside the HSOA. In order to achieve a completely open and interoperable PMI, we review and apply standards of security and architectural design. Moreover, semantic technologies are introduced in decision points for access control allowing the management of a high degree of descriptors by means of ontologies and infer the decision making through rules and reasoners.

XACML profile and implementation for authorization interoperability between OSG and EGEE  

SciTech Connect

The Open Science Grid (OSG) and the Enabling Grids for E-sciencE (EGEE) have a common security model, based on Public Key Infrastructure. Grid resources grant access to users because of their membership in a Virtual Organization (VO), rather than on personal identity. Users push VO membership information to resources in the form of identity attributes, thus declaring that resources will be consumed on behalf of a specific group inside the organizational structure of the VO. Resources contact an access policies repository, centralized at each site, to grant the appropriate privileges for that VO group. Before the work in this paper, despite the commonality of the model, OSG and EGEE used different protocols for the communication between resources and the policy repositories. Hence, middleware developed for one Grid could not naturally be deployed on the other Grid, since the authorization module of the middleware would have to be enhanced to support the other Grid's communication protocol. In addition, maintenance and support for different authorization call-out protocols represents a duplication of effort for our relatively small community. To address these issues, OSG and EGEE initiated a joint project on authorization interoperability. The project defined a common communication protocol and attribute identity profile for authorization call-out and provided implementation and integration with major Grid middleware. The activity had resonance with middleware development communities, such as the Globus Toolkit and Condor, who decided to join the collaboration and contribute requirements and software. In this paper, we discuss the main elements of the profile, its implementation, and deployment in EGEE and OSG. We focus in particular on the operations of the authorization infrastructures of both Grids.

gLExec and MyProxy integration in the ATLAS/OSG PanDA workload management system  

NASA Astrophysics Data System (ADS)

Worker nodes on the grid exhibit great diversity, making it difficult to offer uniform processing resources. A pilot job architecture, which probes the environment on the remote worker node before pulling down a payload job, can help. Pilot jobs become smart wrappers, preparing an appropriate environment for job execution and providing logging and monitoring capabilities. PanDA (Production and Distributed Analysis), an ATLAS and OSG workload management system, follows this design. However, in the simplest (and most efficient) pilot submission approach of identical pilots carrying the same identifying grid proxy, end-user accounting by the site can only be done with application-level information (PanDA maintains its own end-user accounting), and end-user jobs run with the identity and privileges of the proxy carried by the pilots, which may be seen as a security risk. To address these issues, we have enabled PanDA to use gLExec, a tool provided by EGEE which runs payload jobs under an end-user's identity. End-user proxies are pre-staged in a credential caching service, MyProxy, and the information needed by the pilots to access them is stored in the PanDA DB. gLExec then extracts from the user's proxy the proper identity under which to run. We describe the deployment, installation, and configuration of gLExec, and how PanDA components have been augmented to use it. We describe how difficulties were overcome, and how security risks have been mitigated. Results are presented from OSG and EGEE Grid environments performing ATLAS analysis using PanDA and gLExec.

DZero data-intensive computing on the Open Science Grid  

SciTech Connect

High energy physics experiments periodically reprocess data, in order to take advantage of improved understanding of the detector and the data processing code. Between February and May 2007, the DZero experiment has reprocessed a substantial fraction of its dataset. This consists of half a billion events, corresponding to about 100 TB of data, organized in 300,000 files. The activity utilized resources from sites around the world, including a dozen sites participating to the Open Science Grid consortium (OSG). About 1,500 jobs were run every day across the OSG, consuming and producing hundreds of Gigabytes of data. Access to OSG computing and storage resources was coordinated by the SAM-Grid system. This system organized job access to a complex topology of data queues and job scheduling to clusters, using a SAM-Grid to OSG job forwarding infrastructure. For the first time in the lifetime of the experiment, a data intensive production activity was managed on a general purpose grid, such as OSG. This paper describes the implications of using OSG, where all resources are granted following an opportunistic model, the challenges of operating a data intensive activity over such large computing infrastructure, and the lessons learned throughout the project.

The event notification and alarm system for the Open Science Grid operations center  

NASA Astrophysics Data System (ADS)

The Open Science Grid Operations (OSG) Team operates a distributed set of services and tools that enable the utilization of the OSG by several HEP projects. Without these services users of the OSG would not be able to run jobs, locate resources, obtain information about the status of systems or generally use the OSG. For this reason these services must be highly available. This paper describes the automated monitoring and notification systems used to diagnose and report problems. Described here are the means used by OSG Operations to monitor systems such as physical facilities, network operations, server health, service availability and software error events. Once detected, an error condition generates a message sent to, for example, Email, SMS, Twitter, an Instant Message Server, etc. The mechanism being developed to integrate these monitoring systems into a prioritized and configurable alarming system is emphasized.

CDF way to the GRID  

NASA Astrophysics Data System (ADS)

The improvements of the peak instantaneous luminosity of the Tevatron Collider require large increases in computing requirements for the CDF experiment which has to be able to increase proportionally the amount of Monte Carlo data it produces and to satisfy the computing needs for future data analysis. This is, in turn, forcing the CDF Collaboration to move beyond the used dedicated resources and start exploiting Grid resources. CDF has been running a set of CDF Analysis Farm (CAFs), which are submission portals to dedicated pools. In this paper will be presented the CDF strategy to access Grid resources. GlideCAF, a new CAF implementation based on Condor Glide-in technology, has been developed to access resources in specific Grid Sites and is currently in production status at CNAF Tier-1 in Italy. Recently have been configured GlideCAFs also in San Diego (US), Fermilab and Lyon Tier-1 Center (France). GlideCAF model has been used also to implement OsgCAF, which is a Fermilab project to exploit OSG resources in US. LcgCAF is basically a reimplementation of the CAF model in order to access Grid resources by using the LCG/EGEE Middleware components in a total standard Grid way. LcgCAF is constituted by a set of services each of them responsible for accepting, submitting and monitoring CDF user jobs during theirs lifetimes in the Grid environment. An overview of the Grid Environment and of the specific Middleware services used will be presented; GlideCAF and LcgCAF implementations will be discussed in detail. Some details on OsgCAF project will be also given.

A 'hairy' privilege.  

PubMed

Understanding how selected tissue sites establish immune privilege (IP) is of interest to both basic immunology and clinical medicine: it provides novel insights into autoimmunity, fetal and allotransplant rejection and tumor escape from immunosurveillance. Here, we review why the hair follicle can serve as a uniquely accessible, widely available and instructive model for studying the establishment, maintenance, collapse and restoration of IP. The hair follicle epithelium rhythmically generates, maintains and deconstructs an area of relative IP, characterized by very low expression of MHC Ia and suppressed MHC II-dependent antigen presentation, accompanied by the local production of potent immunosuppressants capable of downregulating MHC I (e.g. transforming growth factor-beta1, alpha-melanocyte-stimulating hormone). We discuss the physiological functions of hair follicle IP, illustrate its clinical and therapeutic relevance by focusing on alopecia areata, an autoimmune hair loss disorder, and outline important unanswered questions for future research into one of nature's most intriguing and abundant, yet commonly ignored, sites of IP.

Fermilab supports a scientific program that includes experiments and scientists located across the globe. In order to better serve this community, Fermilab has placed its production computer resources in a Campus Grid infrastructure called 'FermiGrid'. The FermiGrid infrastructure allows the large experiments at Fermilab to have priority access to their own resources, enables sharing of these resources in an opportunistic fashion, and movement of work (jobs, data) between the Campus Grid and National Grids such as Open Science Grid (OSG) and the Worldwide LHC Computing Grid Collaboration (WLCG). FermiGrid resources support multiple Virtual Organizations (VOs), including VOs from the OSG, EGEE, and the WLCG. Fermilab also makes leading contributions to the Open Science Grid in the areas of accounting, batch computing, grid security, job management, resource selection, site infrastructure, storage management, and VO services. Through the FermiGrid interfaces, authenticated and authorized VOs and individuals may access our core grid services, the 10,000+ Fermilab resident CPUs, near-petabyte (including CMS) online disk pools and the multi-petabyte Fermilab Mass Storage System. These core grid services include a site wide Globus gatekeeper, VO management services for several VOs, Fermilab site authorization services, grid user mapping services, as well as job accounting and monitoring, resource selection and data movement services. Access to these services is via standard and well-supported grid interfaces. We will report on the user experience of using the FermiGrid campus infrastructure interfaced to a national cyberinfrastructure - the successes and the problems.

Sertoli cells are immune privileged cells, important for controlling the immune response to male germ cells as well as maintaining the tolerogenic environment in the testis. Additionally, ectopic Sertoli cells have been shown to survive and protect co-grafted cells when transplanted across immunological barriers. The survival of ectopic Sertoli cells has led to the idea that they could be used in cell based gene therapy. In this review, we provide a brief overview of testis immune privilege and Sertoli cell transplantation, factors contributing to Sertoli cell immune privilege, the challenges faced by viral vector gene therapy, the use of immune privileged cells in cell based gene therapy and describe several recent studies on the use of genetically engineered Sertoli cells to provide continuous delivery of therapeutic proteins.

This is a report by an ad hoc committee to the Joint Council of the Society for Vascular Surgery and the International Society for Cardiovascular Surgery (North American Chapter) concerning guidelines that hospitals may use or modify when judging individual applicants for hospital and operating room privileges in vascular surgery. The committee recognizes that the completion of training and obtaining a board certificate is testimony to the qualification but not necessarily the competence of an individual to practice vascular surgery. This report identifies three categories of applicant for privileges in vascular surgery; the surgeon who just completed training, the surgeon who completed training after 1984, and the surgeon who completed training before 1984. In addition, the committee recognizes the importance of periodic vascular surgery privileges renewal for established surgeons. Several pathways are defined for use by hospital privilege committees to evaluate the competence of an individual to be granted privileges in general vascular surgery. The ad hoc committee also has outlined a program for evaluation of established surgeons for renewing privileges in vascular surgery using a mechanism of case outcome audit. Finally, a review mechanism, potential corrective actions, and an appeals mechanism are also suggested. This report represents optimal criteria that may require modification by individual hospitals to meet local community needs and standards. It is the hope of the ad hoc committee that this report will help hospitals and practicing physicians improve the quality of care and treatment outcome in patients with vascular disease.

Resolving least privilege violations in software architectures

Supporting a security principle, such as least privilege, in a software architecture is difficult. Systematic rules are lacking, no guidance explains how to apply the principle in practice. As a result, security principles are often neglected. This lowers the overall security level of the software system and the cost of fixing such problems later on in the development cycle is

ER-Mitochondria Communication. How Privileged?  

NSDL National Science Digital Library

Mitochondria have a low affinity for Ca2+, but they take up these ions during normal cell activity because they are in close proximity to the sites of calcium entry into the cell and of internal Ca2+ release. This gives mitochondria privileged access to cytoplasmic Ca2+ without requiring a direct communication with the endoplasmic reticulum.

CNS immune privilege: hiding in plain sight.  

PubMed

Central nervous system (CNS) immune privilege is an experimentally defined phenomenon. Tissues that are rapidly rejected by the immune system when grafted in sites, such as the skin, show prolonged survival when grafted into the CNS. Initially, CNS immune privilege was construed as CNS isolation from the immune system by the blood-brain barrier (BBB), the lack of draining lymphatics, and the apparent immunoincompetence of microglia, the resident CNS macrophage. CNS autoimmunity and neurodegeneration were presumed automatic consequences of immune cell encounter with CNS antigens. Recent data have dramatically altered this viewpoint by revealing that the CNS is neither isolated nor passive in its interactions with the immune system. Peripheral immune cells can cross the intact BBB, CNS neurons and glia actively regulate macrophage and lymphocyte responses, and microglia are immunocompetent but differ from other macrophage/dendritic cells in their ability to direct neuroprotective lymphocyte responses. This newer view of CNS immune privilege is opening the door for therapies designed to harness autoreactive lymphocyte responses and also implies (i) that CNS autoimmune diseases (i.e. multiple sclerosis) may result as much from neuronal and/or glial dysfunction as from immune system dysfunctions and (ii) that the severe neuronal and glial dysfunction associated with neurodegenerative disorders (i.e. Alzheimer's disease) likely alters CNS-specific regulation of lymphocyte responses affecting the utility of immune-based therapies (i.e. vaccines).

Summary Central nervous system (CNS) immune privilege is an experimentally defined phenomenon. Tissues that are rapidly rejected by the immune system when grafted in sites, such as the skin, show prolonged survival when grafted into the CNS.

Targeting Immune Privilege to Prevent Pathogenic Neovascularization  

PubMed Central

Purpose. Current studies suggest that the immune system plays a critical role in blinding eye disorders. The eye is an immune-privileged site, and FasL expression is a major part of that mechanism because Fas/FasL interactions regulate inflammation and neovascularization, preventing damage to delicate ocular structures. These studies were undertaken to test the idea that modulating immune privilege might be an effective therapeutic approach to pathogenic angiogenesis in the eye. Methods. C57BL/6 mice or FasL-defective B6-gld mice were laser treated to induce choroidal neovascularization (CNV). Mice were injected with cytotoxic FasL in the vitreous cavity or were treated with oral doxycycline in the drinking water. They were evaluated for CNV 7 days later. In some experiments eye tissue was harvested and evaluated for FasL expression, macrophage influx by immunohistochemistry, and release of sFasL. Results. Injection of cytotoxic FasL successfully prevented neovascularization in a mouse model of CNV. Oral doxycycline increased functional FasL in the eye and substantially inhibited neovascularization. Doxycycline treatment increased FasL expression on the RPE cells and reduced circulating and tissue-associated sFasL. Treatment was ineffective in B6-gld mice, demonstrating that CNV inhibition was mediated by FasL. Conclusions. Targeting immune privilege using cytotoxic molecules or by increasing expression of the proapoptotic protein FasL may be a viable approach to treating neovascular eye disease.

Nitrogen containing privileged structures and their solid phase combinatorial synthesis.  

PubMed

The existence of preferred molecular scaffolds that possess inherent biological activity, called privileged structures, is now well recognized. Such privileged structures not only provide enhanced drug-like properties but also give new hits for developing leads. The synthesis of combinatorial libraries, especially with the insertion of privileged substructures into heterocyclic moieties containing nitrogen, provides for a greater probability of the discovery of novel lead compounds using chemical transformation. The review focuses on the progress in the solid-phase synthetic strategies of nitrogen containing privileged structures over the years. PMID:23330874

Labels Matter: Changing the Conversation From “-isms” to Privilege  

NASA Astrophysics Data System (ADS)

Whites typically view racism as discrimination and unfair judgment based on skin color. This view inhibits an end to race-based oppression because it names the issue in terms of the oppressed. A more accurate label is White Privilege. The concept of White privilege is very different from the concept of racism because it includes all Whites, not just those who hold explicit racist views. Acknowledging privilege can be threatening for those who hold a privileged status. However, it is necessary for those who are advantaged to have clarity about their status if the “isms” are to be overcome. In this talk I will discuss my personal struggle to acknowledge my own privileged status (White, American, straight, etc.) and will offer suggestions based on my own experiences for working with advantaged populations committed to overcoming all forms of oppression.

Mechanisms of immune privilege in the posterior eye.  

PubMed

Immune privilege protects vital organs and their functions from the destructive interference of inflammation. Because the eye is easily accessible for surgical manipulation and for assessing and imaging the outcomes, the eye has been a major tissue for the study of immune privilege. Here, we focus on the immune regulatory mechanisms in the posterior eye, in part, because loss of immune privilege may contribute to development of certain retinal diseases in the aging population. We begin with a background in immune privilege and then focus on the select regulatory mechanisms that have been studied in the posterior eye. The review includes a description of the immunosuppressive environment, regulatory surface molecules expressed by cells in the eye, types of cells that participate in immune regulation and finally, discusses animal models of retinal laser injury in the context of mechanisms that overcome immune privilege.

Affective privilege: asymmetric interference by emotional distracters.  

PubMed

Numerous theories posit that affectively salient stimuli are privileged in their capacity to capture attention and disrupt ongoing cognition. Two underlying assumptions in this theoretical position are that the potency of affective stimuli transcends task boundaries (i.e., emotional distracters do not have to belong to a current task-set to disrupt processing) and that there is an asymmetry between emotional and cognitive processing (i.e., emotional distracters disrupt cognitive processing, but not vice versa). These assumptions have remained largely untested, as common experimental probes of emotion-cognition interaction rarely manipulate task-relevance and only examine one side of the presumed asymmetry of interference. To test these propositions directly, a face-word Stroop protocol was adapted to independently manipulate (a) the congruency between target and distracter stimulus features, (b) the affective salience of distracter features, and (c) the task-relevance of emotional compared to non-emotional target features. A three-way interaction revealed interdependent effects of distracter relevance, congruence, and affective salience. Compared to task-irrelevant distracters, task-relevant congruent distracters facilitated performance and task-relevant incongruent distracters impaired performance, but the latter effect depended on the nature of the target feature and task. Specifically, task-irrelevant emotional distracters resulted in equivalent performance costs as task-relevant non-emotional distracters, whereas task-irrelevant non-emotional distracters did not produce performance costs comparable to those generated by task-relevant emotional distracters. These results document asymmetric cross-task interference effects for affectively salient stimuli, supporting the notion of affective prioritization in human information processing. PMID:21954389

Representing User Privileges in Object-Oriented Virtual Reality Systems  

NASA Astrophysics Data System (ADS)

In virtual reality systems which are collaborative and dynamic, i.e. where at run-time mutually interactive objects can be added or removed in different contexts and where their behavior can be modified, the problem of data security and privacy protection is renewed. In such virtual worlds operations on objects should or should not be allowed to users playing particular roles with respect to inter-object interactions. In this paper a method called VR-PR is presented, where privileges are represented by pairs: object - semantic operations induced from object interactions. Semantic operations are generated using automatic analysis of the object method call graphs. Then they are used in the privilege creation and modification process. Privileges based on semantic operations are expressive, flexible and consistent with permanently evolving set of objects composing the virtual world, interactions between the objects, and a set of users.

Progress and Privilege: A book about environmentalism meets the press  

NASA Astrophysics Data System (ADS)

In August 1982, Anchor Press published Progress and Privilege, a book by William Tucker. Tucker's thesis was that environmentalism represented “the ideas of aristocratic conservatism translated onto a popular scale,” and that it had entwined itself with the protection of social and economic privilege. The book was riddled with fundamental errors of fact and of logic, but it also was literate and superficially impressive. It was widely reviewed. An examination of 23 reviews shows this: Most of the reviews in daily newspapers were written by laymen who couldn't analyze Tucker's arguments or recognize his mistakes. Most of the reviews in specialized publications were done by competent analysts who brought some special knowledge to their work. With the latter group of reviewers, Progress and Privilege fared poorly.

Using Hadoop File System and MapReduce in a small/medium Grid site  

NASA Astrophysics Data System (ADS)

Data storage and data access represent the key of CPU-intensive and data-intensive high performance Grid computing. Hadoop is an open-source data processing framework that includes fault-tolerant and scalable distributed data processing model and execution environment, named MapReduce, and distributed File System, named Hadoop distributed File System (HDFS). HDFS was deployed and tested within the Open Science Grid (OSG) middleware stack. Efforts have been taken to integrate HDFS with gLite middleware. We have tested the File System thoroughly in order to understand its scalability and fault-tolerance while dealing with small/medium site environment constraints. To benefit entirely from this File System, we made it working in conjunction with Hadoop Job scheduler to optimize the executions of the local physics analysis workflows. The performance of the analysis jobs which used such architecture seems to be promising, making it useful to follow up in the future.

Migrating Open Science Grid to RPMs*  

NASA Astrophysics Data System (ADS)

We recently completed a significant transition in the Open Science Grid (OSG) in which we moved our software distribution mechanism from the useful but niche system called Pacman to a community-standard native package system, RPM. In this paper we explore some of the lessons learned during this transition as well as our earlier work, lessons that we believe are valuable not only for software distribution and packaging, but also for software engineering in a distributed computing environment where reliability is critical. We discuss the benefits found in moving to a community standard, including the abilities to reuse existing packaging, to donate existing packaging back to the community, and to leverage existing skills in the community. We describe our approach to testing in which we test our software against multiple versions of the OS, including pre-releases of the OS, in order to find surprises before our users do. Finally, we discuss our large-scale evaluation testing and community testing, which are essential for both quality and community acceptance.

Automatic Integration Testbeds validation on Open Science Grid  

NASA Astrophysics Data System (ADS)

A recurring challenge in deploying high quality production middleware is the extent to which realistic testing occurs before release of the software into the production environment. We describe here an automated system for validating releases of the Open Science Grid software stack that leverages the (pilot-based) PanDA job management system developed and used by the ATLAS experiment. The system was motivated by a desire to subject the OSG Integration Testbed to more realistic validation tests. In particular those which resemble to every extent possible actual job workflows used by the experiments thus utilizing job scheduling at the compute element (CE), use of the worker node execution environment, transfer of data to/from the local storage element (SE), etc. The context is that candidate releases of OSG compute and storage elements can be tested by injecting large numbers of synthetic jobs varying in complexity and coverage of services tested. The native capabilities of the PanDA system can thus be used to define jobs, monitor their execution, and archive the resulting run statistics including success and failure modes. A repository of generic workflows and job types to measure various metrics of interest has been created. A command-line toolset has been developed so that testbed managers can quickly submit "VO-like" jobs into the system when newly deployed services are ready for testing. A system for automatic submission has been crafted to send jobs to integration testbed sites, collecting the results in a central service and generating regular reports for performance and reliability.

The Grid

By now almost everyone has heard of 'The Grid', or 'Grid Computing' as it should more properly be described. There are frequent articles in both the popular and scientific press talking about 'The Grid' or about some specific Grid project. Run II Experiments, US-CMS, BTeV, the Sloane Digital Sky Survey and the Lattice QCD folks are all incorporating aspects of Grid Computing in their plans, and the Fermilab Computing Division is supporting and encouraging these efforts. Why are we doing this and what does it have to do with running a physics experiment or getting scientific results? I will explore some of these questions and try to give an overview, not so much of the technical aspects of Grid Computing, rather of what the phenomenon means for our field.

Influence of Immune Privilege on Ocular Tumor Development  

PubMed Central

Mechanisms that maintain ocular immune privilege may contribute to ocular tumor progression by inhibiting tumoricidal immune responses. Consistent with that notion are observations from transplantable tumor models in mice demonstrating that the tumoricidal activity of CD8+ cytolytic T lymphocytes (CTL) may be inhibited directly by interfering with CTL effector function in the eye or indirectly by abrogating the effector function of CD8+ T cell-activated intratumoral macrophages that are critical for ocular tumor rejection. In addition, epigenetic gene regulation by factors within the ocular tumor environment favors the generation of tumor variants that are resistant to CD8+ CTL. Intratumoral macrophages may be essential for eliminating these variants because, unlike CTL, their tumoricidal activity is nonspecific. Hence, the inhibition of macrophage effector function within the eye, presumably to preserve immune privilege by minimizing ocular immunopathology, may hasten the outgrowth of tumor escape variants which contributes to ocular tumor progression.

A theory of biological relativity: no privileged level of causation  

PubMed Central

Must higher level biological processes always be derivable from lower level data and mechanisms, as assumed by the idea that an organism is completely defined by its genome? Or are higher level properties necessarily also causes of lower level behaviour, involving actions and interactions both ways? This article uses modelling of the heart, and its experimental basis, to show that downward causation is necessary and that this form of causation can be represented as the influences of initial and boundary conditions on the solutions of the differential equations used to represent the lower level processes. These insights are then generalized. A priori, there is no privileged level of causation. The relations between this form of ‘biological relativity’ and forms of relativity in physics are discussed. Biological relativity can be seen as an extension of the relativity principle by avoiding the assumption that there is a privileged scale at which biological functions are determined.

Retinal Laser Burn Disrupts Immune Privilege in the Eye  

PubMed Central

Immune privilege allows for the immune protection of the eye in the absence of inflammation. Very few events are capable of overcoming the immune-privileged mechanisms in the eye. In this study, we report that retinal laser burn (RLB) abrogates immune privilege in both the burned and nonburned eye. As early as 6 hours after RLB, and as late as 56 days after RLB, antigen inoculation into the anterior chamber of the burned eye failed to induce peripheral tolerance. After RLB, aqueous humor samples harvested from nontreated eyes but not from either the burned or the contralateral eye, down-regulated the expression of CD40 and up-regulated interleukin-10 mRNA in peritoneal exudate cells, and converted peritoneal exudate cells into tolerogenic antigen-presenting cells (APCs). Unlike F4/80+ APCs from nontreated mice, F4/80+ APCs from RLB mice were unable to transfer tolerance after anterior chamber inoculation of antigen into naïve mice. The increased use of lasers in both the industrial and medical fields raises the risk of RLB-associated loss of immune regulation and an increased risk of immune inflammation in the eye.

The privileged brain representation of first olfactory associations.  

PubMed

Authors, poets, and scientists have been fascinated by the strength of childhood olfactory memories. Indeed, in long-term memory, the first odor-to-object association was stronger than subsequent associations of the same odor with other objects. Here we tested the hypothesis that first odor associations enjoy a privileged brain representation. Because emotion impacts memory, we further asked whether the pleasantness of an odor would influence such a representation. On day 1, we associated the same visual objects initially with one, and subsequently with a second, set of pleasant and unpleasant olfactory and auditory stimuli. One week later, we presented the same visual objects and tested odor-associative memory concurrent with functional magnetic resonance brain imaging. We found that the power (% remembered) of early associations was enhanced when they were unpleasant, regardless of whether they were olfactory or auditory. Brain imaging, however, revealed a unique hippocampal activation for early olfactory but not auditory associations, regardless of whether they were pleasant or unpleasant. Activity within the hippocampus on day 1 predicted the olfactory but not auditory associations that would be remembered one week later. These findings confirmed the hypothesis of a privileged brain representation for first olfactory associations. PMID:19896380

The organization and management of the user support in a global e-science computing infrastructure such as EGEE is one of the challenges of the grid. Given the widely distributed nature of the organisation, and the spread of expertise for installing, configuring, managing and troubleshooting the grid middleware services, a standard centralized model could not be deployed in EGEE. This paper presents the model used in EGEE for building a reliable infrastructure for user, virtual organisation and operations support. The model for supporting a production quality infrastructure for scientific applications will be described in detail. The advantages of the chosen model will be presented and the possible difficulties will be discussed. We will describe the ongoing efforts to build a worldwide grid user support infrastructure in the framework of WLCG by achieving interoperability between the EGEE and OSG user support systems. In this paper we will also describe a scheme of how knowledge management can be used in grid user support and first steps towards a realisation in the framework of the EGEE user support infrastructure.

Progress and privilege: America in the age of environmentalism  

SciTech Connect

Environmentalism, which was a rarity in the 1960s, approaches a national religion in the 1980s, with some environmentalists experiencing pleasure at the prospect of limited resources and no growth. The author explores this new ambivalence toward progress, and concludes that accomplishment can dampen ambition. His analysis of environmentalism as an expression of privilege examines the political and economic characteristics of environmentalists, the major environmental issues, and the public revolt against science to uncover an aristocratic element that is diappearing from our culture. Progress will continue, however, because of global ambitions. The US can build on what has been learned during the Age of Environmentalism and get on with the progress of humanity. 159 references, 1 figure. (DCK)

Novel aspects of corneal angiogenic and lymphangiogenic privilege  

PubMed Central

In this article, we provide the results of experimental studies demonstrating that corneal avascularity is an active process involving the production of anti-angiogenic factors, which counterbalance the proangiogenic/lymphangiogenic factors that are upregulated during wound healing. We also summarize pertinent published reports regarding corneal neovascularization (NV), corneal lymphangiogenesis and corneal angiogenic/lymphangiogenic privilege. We outline the clinical causes of corneal NV, and discuss the angiogenic proteins (VEGF and bFGF) and angiogenesis regulatory proteins. We also describe the role of matrix metalloproteinases MMP-2, -7, and MT1-MMP, anti-angiogenic factors, and lymphangiogenic regulatory proteins during corneal wound healing. Established and potential new therapies for the treatment of corneal neovascularization are also discussed.

Locating privileged spreaders on an online social network  

NASA Astrophysics Data System (ADS)

Social media have provided plentiful evidence of their capacity for information diffusion. Fads and rumors but also social unrest and riots travel fast and affect large fractions of the population participating in online social networks (OSNs). This has spurred much research regarding the mechanisms that underlie social contagion, and also who (if any) can unleash system-wide information dissemination. Access to real data, both regarding topology—the network of friendships—and dynamics—the actual way in which OSNs users interact, is crucial to decipher how the former facilitates the latter's success, understood as efficiency in information spreading. With the quantitative analysis that stems from complex network theory, we discuss who (and why) has privileged spreading capabilities when it comes to information diffusion. This is done considering the evolution of an episode of political protest which took place in Spain, spanning one month in 2011.

Service chief recommendations in performance-based clinical privileging.  

PubMed

A medical facility is responsible for the standards of practice of its medical staff and can be found liable if it was negligent in appointing or reappointing a member of the staff who is incompetent. Joint Commission standards require that recommendations for consideration of initial, renewal, or revision of clinical privileges be made based upon peer evaluations of professional performance, judgment, and clinical and technical skills. Valid recommendations involve two discrete steps: collecting data and evaluating that data. The most pertinent data are those of current competence. The responsibility of interpreting the data rests with the Department or Service Chief. It is his clinical experience that enables him to evaluate a providers' care, in light of accepted standards of practice, for a specialty and for a specific region. Subsequently, in order for the Credentials Committee to make a meaningful performance-based privileging recommendation to the military treatment facility Commander, a summary must be written by the Department/Service Chief, incorporating all of the relevant data and the evaluation of those data. Based on the objective data with the accompanying evaluation, the summary must conclude that the provider is physically and mentally capable of performing the procedures requested, including having the social skills necessary to relate with others in the total care of the patient, and that his training, experience, and recent past performance is consistent with the prudent delivery of care. Continuous performance improvement strategies must support this process by organizing hospital committee structures, ancillary staffing, and information management processes to support a decision-making process based on facts.

See no evil, hear no evil, do no evil: the lessons of immune privilege.  

PubMed

Immune-mediated inflammation and allograft rejection are greatly reduced in certain organs, a phenomenon called 'immune privilege'. Immune privilege is well developed in three regions of the body: the eye, the brain and the pregnant uterus. Immune-mediated inflammation has devastating consequences in the eye and brain, which have limited capacity for regeneration. Likewise, loss of immune privilege at the maternal-fetal interface culminates in abortion in rodents. However, all three regions share many adaptations that restrict the induction and expression of immune-mediated inflammation. A growing body of evidence from rodent studies suggests that a breakdown in immune privilege contributes to multiple sclerosis, uveitis, corneal allograft rejection and possibly even immune abortion.

Waiver of the psychotherapist-patient privilege: implications for child custody litigation.  

PubMed

The psychotherapist-patient privilege, rooted in both common and statutory law, is predicated upon the public policy goal of protecting the reasonable expectation of privacy of individuals seeking psychotherapy. The privilege is not absolute, however. State and federal courts are far from uniform in determining how and when the privilege should be waived, in whole or in part, through implication, inadvertence or the affirmative action of the parties. In the family law context, the law that has evolved around the exercise of this privilege is even more complex as the needs of children add another wrinkle to the goal of balancing the imperative of confidentiality with the need for useful information that may be provided.

Customers' expectations of complaint handling by airline service: privilege status and reasonability of demands from a social learning perspective.  

PubMed

In the airline industry, membership and cabin class are noticeable servicescape features of customers' privilege status. Customers may learn that higher privilege customers are more desired and endured by the airline. From the customers' point of view, those with higher privilege may expect their demands to be complied with when they complain. The present study employed hypothetical scenarios to investigate how the privilege status of passengers and reasonability of their demands influenced their expectations toward the compliance of airline personnel. Analysis showed that higher privilege customers were more likely to expect airline personnel to comply with their demands. Moreover, participants with medium or high levels of privilege status had greater expectations of compliance even when demands were unreasonable. In sum, customer expectations toward complaint handling reflected predictions based on social learning. PMID:19610476

The assessment of epididymal lymphatics within the concept of immunologically privileged sites.  

PubMed

This paper seeks to provide background information for future studies of immunological responses in the epididymis. Immunologically privileged sites afford anomalous protection to foreign grafts and this is usually thought to be related to absence of intrinsic lymphatics. A search through the literature reveals lack of any attempt to implant foreign tissue into this organ. The present investigation was undertaken to consider the presence, if any, of lymphatic channels within the connective tissue framework of rat epididymis. The tissues were taken through for histology and examined with light and electron microscopes. Contrary to anticipation, there are abundant lymphatic channels within the epididymal tissue. In the discussion a hypothesis is raised that the epididymis may not be an immunologically privileged site or that if any privilege, the explanation will not be related to absence of terminal lymphatics in this area. Further work in progress seeks to clarify this hypothesis. PMID:6605461

Membrane Fas ligand activates innate immunity and terminates ocular immune privilege.  

PubMed

It has been proposed that the constitutive expression of Fas ligand (FasL) in the eye maintains immune privilege, in part through inducing apoptosis of infiltrating Fas(+) T cells. However, the role of FasL in immune privilege remains controversial due to studies that indicate FasL is both pro- and anti-inflammatory. To elucidate the mechanism(s) by which FasL regulates immune privilege, we used an ocular tumor model and examined the individual roles of the membrane-bound and soluble form of FasL in regulating ocular inflammation. Following injection into the privileged eye, tumors expressing only soluble FasL failed to trigger inflammation and grew progressively. By contrast, tumors expressing only membrane FasL 1) initiated vigorous neutrophil-mediated inflammation, 2) terminated immune privilege, and 3) were completely rejected. Moreover, the rejection coincided with activation of both innate and adaptive immunity. Interestingly, a higher threshold level of membrane FasL on tumors is required to initiate inflammation within the immune privileged eye, as compared with nonprivileged sites. The higher threshold is due to the suppressive microenvironment found within aqueous humor that blocks membrane FasL activation of neutrophils. However, aqueous humor is unable to completely block the proinflammatory effects of tumor cells that express high levels of membrane FasL. In conclusion, our data indicate that the function of FasL on intraocular tumors is determined by the microenvironment in conjunction with the form and level of FasL expressed. PMID:12193747

Predicting the Performance of a GRID Environment: An Initial Effort to Increase Scheduling Efficiency  

NASA Astrophysics Data System (ADS)

GRID environments are privileged targets for computation-intensive problem solving in areas from weather forecasting to seismic analysis. Mainly composed by commodity hardware, these environments can deliver vast computational capacity, at relatively low cost. In order to take full advantage of their power we need to have efficient task schedulers with the ability to maximize resource effectiveness, shortening execution times. GRID schedulers must not only decide taking a snapshot of the GRID's status into account, but should also consider the output involved in past decisions. In this work, we intend to show how resource usage can be analyzed, through the use of data mining techniques, to predict performance availability of a GRID environment, as a preliminary work to increase scheduling efficiency as well as adequate resource provisioning.

A Grid Cataloging System  

NASA Astrophysics Data System (ADS)

Grid computing typically involves a large number of grid and scientific research collaborations with different computing needs. In grid computing, the needs are provided by distributed computing sites with computing resources and storage resources for participating research collaborations. In each site which provides such grid resources, it is necessary for the distributed computing resources to be monitored constantly. Then, the status of the monitored site information needs to be accurately presented to the collaborators. The monitored site information can be presented in the form of catalog for each site in a single web page which summarizes the status of each participating sites. Then, based on the information presented in the cataloging system, computing can be scheduled or participating grid site's status can be checked easily. We have designed a grid site status cataloging system to be used for such purpose. We present a grid cataloging system called the Gridcat. The Gridcat stores monitored information to a database using the back-end scripts. The back-end scripts are used to access to information on the grid computing resources, perform grid tests proactively, query against each grid site, and finally store all the information gathered to a database. The web front-end scripts presents a summary of site status at a certain time. The Gridcat can be easily plugged into existing web servers that serves grid site status and can provide an easy grid cataloging with combination of other grid monitoring components.

Method of grid generation  

DOEpatents

The present invention provides a method of grid generation that uses the geometry of the problem space and the governing relations to generate a grid. The method can generate a grid with minimized discretization errors, and with minimal user interaction. The method of the present invention comprises assigning grid cell locations so that, when the governing relations are discretized using the grid, at least some of the discretization errors are substantially zero. Conventional grid generation is driven by the problem space geometry; grid generation according to the present invention is driven by problem space geometry and by governing relations. The present invention accordingly can provide two significant benefits: more efficient and accurate modeling since discretization errors are minimized, and reduced cost grid generation since less human interaction is required.

Creating immune privilege: active local suppression that benefits friends, but protects foes

Natural regulatory mechanisms prevent inappropriate immune activation to self and innocuous foreign antigens. Here, we adapt the notion of immune privilege, which was originally applied to transplanted tissues, to consider how antigenic tumour cells and chronic pathogens might exploit natural regulatory mechanisms to become non-immunogenic. This conceptual approach reveals new mechanistic perspectives that may help to explain the paradoxical persistence

Understanding The Smart Grid  

SciTech Connect

The report provides an overview of what the Smart Grid is and what is being done to define and implement it. The electric industry is preparing to undergo a transition from a centralized, producer-controlled network to a decentralized, user-interactive one. Not only will the technology involved in the electric grid change, but the entire business model of the industry will change too. A major objective of the report is to identify the changes that the Smart Grid will bring about so that industry participants can be prepared to face them. A concise overview of the development of the Smart Grid is provided. It presents an understanding of what the Smart Grid is, what new business opportunities or risks might come about due to its introduction, and what activities are already taking place regarding defining or implementing the Smart Grid. This report will be of interest to the utility industry, energy service providers, aggregators, and regulators. It will also be of interest to home/building automation vendors, information technology vendors, academics, consultants, and analysts. The scope of the report includes an overview of the Smart Grid which identifies the main components of the Smart Grid, describes its characteristics, and describes how the Smart Grid differs from the current electric grid. The overview also identifies the key concepts involved in the transition to the Smart Grid and explains why a Smart Grid is needed by identifying the deficiencies of the current grid and the need for new investment. The report also looks at the impact of the Smart Grid, identifying other industries which have gone through a similar transition, identifying the overall benefits of the Smart Grid, and discussing the impact of the Smart Grid on industry participants. Furthermore, the report looks at current activities to implement the Smart Grid including utility projects, industry collaborations, and government initiatives. Finally, the report takes a look at key technology providers involved in the Smart Grid and provides profiles on them including contact information, company overviews, technology reviews, and key Smart Grid activities.

Securing smart grid technology  

NASA Astrophysics Data System (ADS)

In the developing countries electrical energy is very important for its all-round improvement by saving thousands of dollars and investing them in other sector for development. For Growing needs of power existing hierarchical, centrally controlled grid of the 20th Century is not sufficient. To produce and utilize effective power supply for industries or people we should have Smarter Electrical grids that address the challenges of the existing power grid. The Smart grid can be considered as a modern electric power grid infrastructure for enhanced efficiency and reliability through automated control, high-power converters, modern communications infrastructure along with modern IT services, sensing and metering technologies, and modern energy management techniques based on the optimization of demand, energy and network availability and so on. The main objective of this paper is to provide a contemporary look at the current state of the art in smart grid communications as well as critical issues on smart grid technologies primarily in terms of information and communication technology (ICT) issues like security, efficiency to communications layer field. In this paper we propose new model for security in Smart Grid Technology that contains Security Module(SM) along with DEM which will enhance security in Grid. It is expected that this paper will provide a better understanding of the technologies, potential advantages and research challenges of the smart grid and provoke interest among the research community to further explore this promising research area.

Parental Reasoning, Denying Privileges, Yelling, and Spanking: Ethnic Differences and Associations with Child Externalizing Behavior  

PubMed Central

Synopsis Objective This study was designed to examine whether African American and European American mothers differ in their discipline use when reasoning, denying privileges, yelling, and spanking are considered simultaneously and whether there are ethnic group differences in how these four forms of discipline are associated with child externalizing behavior. Design Structural equation models were used to examine relations between children's externalizing behavior in kindergarten (age 5), mothers' discipline in grades 1-3 (ages 6-8), and children's externalizing behavior in grade 4 (age 9) in a sample of 585 mothers and children. Results African American and European American mothers showed the same rank order frequency of reported use of each of the four forms of discipline, most frequently using reasoning, followed by yelling, denying privileges, and least frequently spanking. However, European American mothers more frequently reported using three of the four forms of discipline than did African American mothers, with no ethnic differences in the frequency with which mothers reported spanked. For European American children, higher levels of teacher-reported child externalizing in kindergarten predicted mothers' more frequent report of denying privileges, yelling, and spanking in grades 1-3; only spanking was associated with more child externalizing behaviors in grade 4. For African American children, teacher-reported child externalizing in kindergarten was unrelated to mothers' report of discipline in grades 1-3; considering predictions from discipline to grade 4 child externalizing, only denying privileges was predictive. Conclusions European American and African American families differ in links between children's teacher-reported externalizing behaviors and subsequent mother-reported discipline as well as links between mother-reported discipline and children's subsequent teacher-reported externalizing.

A faculty group practice-driven credentialing and privileging infrastructure in a school of dental medicine.  

PubMed

Credentialing and assigning clinical privileges are well-established practices in institutions that need to verify a clinician's ability to provide direct patient care services. The credentialing process verifies a provider's credentials to practice his or her profession, while privileging authorizes the individual to perform enumerated procedures within a specific scope of practice. All clinical faculty members at Harvard School of Dental Medicine (HSDM) practice in the Faculty Group Practice (FGP). Because of the number of practitioners in the FGP, the organization instituted a more formal process of credentialing that verifies that practitioners are not only licensed to practice, but also are competent to provide direct patient care. In contrast to other dental schools that have established similar protocols, HSDM approached the process not from the academic side, but rather from the clinical practice side, explicitly taking into account whether the FGP could accommodate another practitioner when an academic department wished to appoint a new faculty member. In doing so, we had to be careful to reconcile our educational and research needs with those of the FGP. In this article, we describe how, within this framework, we established a credentialing and privileging program in which all full- and part-time faculty members, as well as advanced graduate students, were included.

Challenges facing production grids

Today's global communities of users expect quality of service from distributed Grid systems equivalent to that their local data centers. This must be coupled to ubiquitous access to the ensemble of processing and storage resources across multiple Grid infrastructures. We are still facing significant challenges in meeting these expectations, especially in the underlying security, a sustainable and successful economic model, and smoothing the boundaries between administrative and technical domains. Using the Open Science Grid as an example, I examine the status and challenges of Grids operating in production today.

Anisotropic Cartesian Grid Adaptation  

NASA Astrophysics Data System (ADS)

A three-dimensional grid adaptation method using the concept of anisotropic Cartesian grid has been developed to improve the efficiency of an existing Cartesian grid adaptation method by reducing the total number of cells needed to compute a flow field. The present grid adaptation is carried out by performing both grid coarsening and refinement in such a way that the cell aspect ratio can take an arbitrary value, keeping the grid smoothness. This flexibility necessitates the concept of unstructured approach. Two test cases: a cylinder in supersonic flow and an ONERA M6 wing in transonic flow show that the present method can well capture 2D and 3D flow features. In the cylinder case, the number of cells after the final adaptation cycle is one or two orders of magnitude less than that of the corresponding isotropic grid; in the ONERA M6 case it becomes about half as many. This remarkable saving in the 2D case is achieved because the spanwise domain is covered by only one cell in the present method, unlike conventional isotropic approaches. As a result of the decrease in the number of cells, the anisotropic grid requires less time to solve the flow and less amount of total memory, though the amount of memory per cell actually increases because of its unstructured property.

Security for grids  

SciTech Connect

Securing a Grid environment presents a distinctive set of challenges. This paper groups the activities that need to be secured into four categories: naming and authentication; secure communication; trust, policy, and authorization; and enforcement of access control. It examines the current state of the art in securing these processes and introduces new technologies that promise to meet the security requirements of Grids more completely.

Grid Computing and Applications  

ScienceCinema

'Grid' computing has emerged as an important new field, distinguished from conventional distributed computing by its focus on large-scale resource sharing, innovative applications, and, in some cases, high-performance orientation. In this talk, Dr. Foster defines this new field. First, he reviews the 'Grid problem,' which he defines as flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions, and resources - what he refers to as virtual organizations. In such settings, we encounter unique authentication, resource access, resource discovery, and other challenges. It is this class of problem that is addressed by Grid technologies. He presents an extensible and open Grid architecture, in which protocols, services, application programming interfaces, and software development kits are categorized according to their roles in enabling resource sharing. He also reviews major Grid projects worldwide and describes how they are contributing to the realization of this architecture.

The Privileged Chemical Space Predictor (PCSP): A computer program that identifies privileged chemical space from screens of modularly assembled chemical libraries  

PubMed Central

Modularly assembled combinatorial libraries are often used to identify ligands that bind to and modulate the function of a protein or a nucleic acid. Much of the data from screening these compounds, however, is not efficiently utilized to define structure-activity relationships (SAR). If SAR data are accurately constructed, it can enable the design of more potent binders. Herein, we describe a computer program called Privileged Chemical Space Predictor (PCSP) that statistically determines SAR from high-throughput screening (HTS) data and then identifies features in small molecules that predispose them for binding a target. Features are scored for statistical significance and can be utilized to design improved second generation compounds or more target-focused libraries. The program’s utility is demonstrated through analysis of a modularly assembled peptoid library that was screened for binding to and inhibiting a group I intron RNA from the fungal pathogen Candida albicans.

``Yin-Yang grid'': An overset grid in spherical geometry  

NASA Astrophysics Data System (ADS)

A new kind of overset grid, named Yin-Yang grid, for spherical geometry is proposed. The Yin-Yang grid is composed of two identical component grids that are combined in a complemental way to cover a spherical surface with partial overlap on their boundaries. Each component grid is a low-latitude part of the latitude-longitude grid. Therefore the grid spacing is quasi-uniform, and the metric tensors are simple and analytically known. One can directly apply mathematical and numerical resources that have been written in the spherical polar coordinates or latitude-longitude grid. The complemental combination of the two identical component grids enables us to make efficient and concise programs. Simulation codes for geodynamo and mantle convection simulations using finite difference scheme based on the Yin-Yang grid are developed and tested. The Yin-Yang grid is suitable for massively parallel computers.

Orthogonal grid generation  

NASA Astrophysics Data System (ADS)

A technique is presented for the generation of two-dimensional orthogonal grids which is accurate, rapid, conceptually simple, relatively robust, and general enough to be applicable to a wide range of applications when coupled with modern flow solvers. A novel application of the hinge point transformation is used to map a contour onto a half plane, which is thereby transformed into an open rectangle, where the points added to close the rectangle and grid boundary point locations are specified according to preselected stretchings. Exponential spline interpolation determines the physical plane locations corresponding to the grid boundary point locations on three sides of the rectangle, and physical locations corresponding to the fourth side are obtained by inverting the transformations. A fast Poisson solver is then used to determine the physical location of the interior grid nodes. A method for building complex multiple region grids through the matching of simpler grids at common boundaries is illustrated. Suitable grids can be produced for a wide range of nonperiodic geometries.

The DESY Grid Centre  

NASA Astrophysics Data System (ADS)

DESY is one of the world-wide leading centers for research with particle accelerators, synchrotron light and astroparticles. DESY participates in LHC as a Tier-2 center, supports on-going analyzes of HERA data, is a leading partner for ILC, and runs the National Analysis Facility (NAF) for LHC and ILC in the framework of the Helmholtz Alliance, Physics at the Terascale. For the research with synchrotron light major new facilities are operated and built (FLASH, PETRA-III, and XFEL). DESY furthermore acts as Data-Tier1 centre for the Neutrino detector IceCube. Established within the EGI-project DESY operates a grid infrastructure which supports a number of virtual Organizations (VO), incl. ATLAS, CMS, and LHCb. Furthermore, DESY hosts some of HEP and non-HEP VOs, such as the HERA experiments and ILC as well as photon science communities. The support of the new astroparticle physics VOs IceCube and CTA is currently set up. As the global structure of the grid offers huge resources which are perfect for batch-like computing, DESY has set up the National Analysis Facility (NAF) which complements the grid to allow German HEP users for efficient data analysis. The grid infrastructure and the NAF use the same physics data which is distributed via the grid. We call the conjunction of grid and NAF the DESY Grid Centre. In the contribution to CHEP2012 we will in depth discuss the conceptional and operational aspects of our multi-VO and multi-community Grid Centre and present the system setup. We will in particular focus on the interplay of Grid and NAF and present experiences of the operations.

Immunoprotective properties of primary Sertoli cells in mice: potential functional pathways that confer immune privilege.  

PubMed

Primary Sertoli cells isolated from mouse testes survive when transplanted across immunological barriers and protect cotransplanted allogeneic and xenogeneic cells from rejection in rodent models. In contrast, the mouse Sertoli cell line (MSC-1) lacks immunoprotective properties associated with primary Sertoli cells. In this study, enriched primary Sertoli cells or MSC-1 cells were transplanted as allografts into the renal subcapsular area of naive BALB/c mice, and their survival in graft sites was compared. While Sertoli cells were detected within the grafts with 100% graft survival throughout the 20-day study, MSC-1 cells were rejected between 11 and 14 days, with 0% graft survival at 20 days posttransplantation. Nonetheless, the mechanism for primary Sertoli cell survival and immunoprotection remains unresolved. To identify immune factors or functional pathways potentially responsible for immune privilege, gene expression profiles of enriched primary Sertoli cells were compared with those of MSC-1 cells. Microarray analysis identified 2369 genes in enriched primary Sertoli cells that were differentially expressed at ±4-fold or higher levels than in MSC-1 cells. Ontological analyses identified multiple immune pathways, which were used to generate a list of 340 immune-related genes. Three functions were identified in primary Sertoli cells as potentially important for establishing immune privilege: suppression of inflammation by specific cytokines and prostanoid molecules, slowing of leukocyte migration by controlled cell junctions and actin polymerization, and inhibition of complement activation and membrane-associated cell lysis. These results increase our understanding of testicular immune privilege and, in the long-term, could lead to improvements in transplantation success. PMID:21900683

IDL Grid Web Portal  

NASA Astrophysics Data System (ADS)

Image Data Language is a software for data analysis, visualization and cross-platform application development. The potentiality of IDL is well-known in the academic scientific world, especially in the astronomical environment where thousands of procedures are developed by using IDL. The typical use of IDL is the interactive mode but it is also possible to run IDL programs that do not require any interaction with the user, submitting them in batch or background modality. Through the interactive mode the user immediately receives images or other data produced in the running phase of the program; in batch or background mode, the user will have to wait for the end of the program, sometime for many hours or days to obtain images or data that IDL produced as output: in fact in Grid environment it is possible to access to or retrieve data only after completion of the program. The work that we present gives flexibility to IDL procedures submitted to the Grid computer infrastructure. For this purpose we have developed an IDL Grid Web Portal to allow the user to access the Grid and to submit IDL programs granting a full job control and the access to images and data generated during the running phase, without waiting for their completion. We have used the PHP technology and we have given the same level of security that Grid normally offers to its users. In this way, when the user notices that the intermediate program results are not those expected, he can stop the job, change the parameters to better satisfy the computational algorithm and resubmit the program, without consuming the CPU time and other Grid resources. The IDL Grid Web Portal allows you to obtain IDL generated images, graphics and data tables by using a normal browser. All conversations from the user and the Grid resources occur via Web, as well as authentication phases. The IDL user has not to change the program source much because the Portal will automatically introduce the appropriate modification before submitting the IDL program to the Grid. When the user wishes, he will be able to check the status of his program and outputs, if any, because the Portal will assign the users a specific and univocal session identification number. This Web portal runs in the Trinacria Grid Virtual Laboratory and fully exploits the power of this grid in terms of CPU and data storage.

Grid in Geosciences  

NASA Astrophysics Data System (ADS)

The worldwide Earth science community covers a mosaic of disciplines and players such as academia, industry, national surveys, international organizations, and so forth. It provides a scientific basis for addressing societal issues, which require that the Earth science community utilize massive amounts of data, both in real and remote time. This data is usually distributed among many different organizations and data centers. These facts, the utilization of massive, distributed data amounts, explain the interest of the Earth science community for Grid technology, also noticeable by the variety of applications ported and tools developed. In parallel to the participation in EGEE, other projects involving ES disciplines were or have been carried out as related projects to EGEE (Enabling Grids for E-sciencE) such as CYCLOPS, SEEGrid, EELA2, EUASIA or outside e.g., in the framework of WGISS/CEOS. Numerous applications in atmospheric chemistry, meteorology, seismology, hydrology, pollution, climate and biodiversity were deployed successfully on Grid. In order to fulfill requirements of risk management, several prototype applications have been deployed using OGC (Open geospatial Consortium) components with Grid middleware. Examples are in hydrology for flood or Black Sea Catchment monitoring, and in fire monitoring. Meteorological, pollution and climate applications are based on meteorological models ported on Grid such as MM5 (Mesoscale Model), WRF (Weather Research and Forecasting), RAMS (Regional Atmospheric Modeling System) or CAM (Community Atmosphere Model). Seismological applications on Grid are numerous in locations where their occurrence is important and computer resources too small; then interfaces and gateways have been developed to facilitate the access to data and specific software and avoid work duplication. A portal has been deployed for commercial seismological software, Geocluster, for academic users. In this presentation examples of such applications will be presented to point out the potentiality of Grid for research and operation. Grid provides large amount of compute resources but is also an interesting e-collaboration platform, important for geosciences projects.

Beyond grid security  

NASA Astrophysics Data System (ADS)

While many fields relevant to Grid security are already covered by existing working groups, their remit rarely goes beyond the scope of the Grid infrastructure itself. However, security issues pertaining to the internal set-up of compute centres have at least as much impact on Grid security. Thus, this talk will present briefly the EU ISSeG project (Integrated Site Security for Grids). In contrast to groups such as OSCT (Operational Security Coordination Team) and JSPG (Joint Security Policy Group), the purpose of ISSeG is to provide a holistic approach to security for Grid computer centres, from strategic considerations to an implementation plan and its deployment. The generalised methodology of Integrated Site Security (ISS) is based on the knowledge gained during its implementation at several sites as well as through security audits, and this will be briefly discussed. Several examples of ISS implementation tasks at the Forschungszentrum Karlsruhe will be presented, including segregation of the network for administration and maintenance and the implementation of Application Gateways. Furthermore, the web-based ISSeG training material will be introduced. This aims to offer ISS implementation guidance to other Grid installations in order to help avoid common pitfalls.

A critical consideration of the rat epididymis as an immunologically privileged site.  

PubMed

A literature search reveals a lack of any previous attempt to implant foreign tissue into the epididymis. Instead, related studies have been carried out within the adjacent testis. Theoretically, there are peculiar immunobiological factors that can require separate consideration of the two adjacent sites. With this background, we designed the present work by removing the adjacent testis and subsequently used biochemical, histological, and electron microscopic methods to assess the fate of parathyroid allografts buried within the epididymis. Since the concept of immunological privilege is usually explained on the basis of the nature of lymphatic drainage, we also studied the pattern of lymphatic drainage at each allograft bed. In the analysis of our results, the animals were grouped according to the nature of lymph pattern from each transplant bed. We observed that prolonged survival of the tissue allograft occurred only when the lymphatic trunk draining the graft bed bypassed all retroperitoneal nodes and opened directly into the blood stream via the cisterna chyli. This anomalous survival is favoured by pretransplant splenectomy. These results demonstrate that the rat epididymis can sometimes be immunologically privileged. PMID:3340825

Healthcare access as a right, not a privilege: a construct of Western thought  

PubMed Central

Over 45 million Americans are uninsured or underinsured. Those living in poverty exhibit the worst health status. Employment, education, income, and race are important factors in a person's ability to acquire healthcare access. Having established that there are people lacking healthcare access due to multi-factorial etiologies, the question arises as to whether the intervention necessary to assist them in obtaining such access should be considered a privilege, or a right. The right to healthcare access is examined from the perspective of Western thought. Specifically through the works of Aristotle, Immanuel Kant, Thomas Hobbes, Thomas Paine, Hannah Arendt, James Rawls, and Norman Daniels, which are accompanied by a contemporary example of intervention on behalf of the medically needy by the The Johns Hopkins Urban Health Institute. As human beings we are all valuable social entities whereby, through the force of morality, through implicitly forged covenants among us as individuals and between us and our governments, and through the natural rights we maintain as individuals and those we collectively surrender to the common good, it has been determined by nature, natural laws, and natural rights that human beings have the right, not the privilege, to healthcare access.

The initial federal funding for the Colorado State University Smart Grid Integration Laboratory is through a Congressionally Directed Project (CDP), DE-OE0000070 Smart Grid Integration Laboratory. The original program requested in three one-year increments for staff acquisition, curriculum development, and instrumentation â?? all which will benefit the Laboratory. This report focuses on the initial phase of staff acquisition which was directed and administered by DOE NETL/ West Virginia under Project Officer Tom George. Using this CDP funding, we have developed the leadership and intellectual capacity for the SGIC. This was accomplished by investing (hiring) a core team of Smart Grid Systems engineering faculty focused on education, research, and innovation of a secure and smart grid infrastructure. The Smart Grid Integration Laboratory will be housed with the separately funded Integrid Laboratory as part of CSUâ??s overall Smart Grid Integration Center (SGIC). The period of performance of this grant was 10/1/2009 to 9/30/2011 which included one no cost extension due to time delays in faculty hiring. The Smart Grid Integration Laboratoryâ??s focus is to build foundations to help graduate and undergraduates acquire systems engineering knowledge; conduct innovative research; and team externally with grid smart organizations. Using the results of the separately funded Smart Grid Workforce Education Workshop (May 2009) sponsored by the City of Fort Collins, Northern Colorado Clean Energy Cluster, Colorado State University Continuing Education, Spirae, and Siemens has been used to guide the hiring of faculty, program curriculum and education plan. This project develops faculty leaders with the intellectual capacity to inspire its students to become leaders that substantially contribute to the development and maintenance of Smart Grid infrastructure through topics such as: (1) Distributed energy systems modeling and control; (2) Energy and power conversion; (3) Simulation of electrical power distribution system that integrates significant quantities of renewable and distributed energy resources; (4) System dynamic modeling that considers end-user behavior, economics, security and regulatory frameworks; (5) Best practices for energy management IT control solutions for effective distributed energy integration (including security with the underlying physical power systems); (6) Experimental verification of effects of various arrangements of renewable generation, distributed generation and user load types along with conventional generation and transmission. Understanding the core technologies for enabling them to be used in an integrated fashion within a distribution network remains is a benefit to the future energy paradigm and future and present energy engineers.

Diversity-oriented general protocol for the synthesis of privileged oxygen scaffolds: pyrones, coumarins, benzocoumarins and naphthocoumarins.  

PubMed

A new general methodology for the synthesis of various functionalized privileged oxygen heterocyclic scaffolds, viz. pyrones, coumarins, and benzannulated coumarins, is developed. The synthesis proceeds through carbanion-induced ring transformation of lactones with various methylene carbonyl compounds followed by DDQ-mediated unprecedented oxidative cleavage of oxaylidenes intermediates. Studies of the mechanism of the conversions of oxaylidene intermediates into corresponding carbonyl compounds in the presence of DDQ revealed that the reactions took place via the formation of a Michael adduct instead of an intermolecular charge transfer complex. The methodology offers the fabrication of diverse privileged scaffolds with tolerance for many functional groups onto the oxygen heterocyclic molecular framework. PMID:23824305

NREL Smart Grid Projects

Although implementing Smart Grid projects at the distribution level provides many advantages and opportunities for advanced operation and control, a number of significant challenges must be overcome to maintain the high level of safety and reliability that the modern grid must provide. For example, while distributed generation (DG) promises to provide opportunities to increase reliability and efficiency and may provide grid support services such as volt/var control, the presence of DG can impact distribution operation and protection schemes. Additionally, the intermittent nature of many DG energy sources such as photovoltaics (PV) can present a number of challenges to voltage regulation, etc. This presentation provides an overview a number of Smart Grid projects being performed by the National Renewable Energy Laboratory (NREL) along with utility, industry, and academic partners. These projects include modeling and analysis of high penetration PV scenarios (with and without energy storage), development and testing of interconnection and microgrid equipment, as well as the development and implementation of advanced instrumentation and data acquisition used to analyze the impacts of intermittent renewable resources. Additionally, standards development associated with DG interconnection and analysis as well as Smart Grid interoperability will be discussed.

The Computing Grids  

NASA Astrophysics Data System (ADS)

Since the beginning of the millennium, High Energy Physics research institutions like CERN and INFN pioneered several projects aimed at exploiting the synergy among computing power, storage and network resources, and creating an infrastructure of distributed computing on a worldwide scale. In the year 2000, after the Monarch project [http://monarc.web.cern.ch/MONARC/], DataGrid started [http://eu-datagrid.web.cern.ch/eu-datagrid/] aimed at providing High Energy Physics with the computing power needed for the LHC enterprise. This program evolved into the EU DataGrid project, that implemented the first actual prototype of a Grid middleware running on a testbed environment. The next step consisted in the application to the LHC experiments, with the LCG project [http://lcg.web.cern.ch/LCG/], in turn followed by the EGEE [http://www.eu-egee.org/] and EGEE II programs.

Grids in mammography  

SciTech Connect

A special soft-tissue grid reduced scattered radiation to the receptor and resulted in improved contrast and visibility of small structures to the degree that increased kVp could be used during screen-film mammography. The reduction in radiation to the skin that is associated with the more penetrating higher kVp technique more than compensated for the Bucky factor of the grid. This technique allowed for better penetration of the base of large, dense breasts without the use of vigorous compression. Results that were obtained with a faster (2X) film are also presented and discussed.

Essential Grid Workflow Monitoring Elements  

SciTech Connect

Troubleshooting Grid workflows is difficult. A typicalworkflow involves a large number of components networks, middleware,hosts, etc. that can fail. Even when monitoring data from all thesecomponents is accessible, it is hard to tell whether failures andanomalies in these components are related toa given workflow. For theGrid to be truly usable, much of this uncertainty must be elim- inated.We propose two new Grid monitoring elements, Grid workflow identifiersand consistent component lifecycle events, that will make Gridtroubleshooting easier, and thus make Grids more usable, by simplifyingthe correlation of Grid monitoring data with a particular Gridworkflow.

Changing from computing grid to knowledge grid in life-science grid.  

PubMed

Grid computing has a great potential to become a standard cyber infrastructure for life sciences that often require high-performance computing and large data handling, which exceeds the computing capacity of a single institution. Grid computer applies the resources of many computers in a network to a single problem at the same time. It is useful to scientific problems that require a great number of computer processing cycles or access to a large amount of data.As biologists,we are constantly discovering millions of genes and genome features, which are assembled in a library and distributed on computers around the world.This means that new, innovative methods must be developed that exploit the re-sources available for extensive calculations - for example grid computing.This survey reviews the latest grid technologies from the viewpoints of computing grid, data grid and knowledge grid. Computing grid technologies have been matured enough to solve high-throughput real-world life scientific problems. Data grid technologies are strong candidates for realizing a "resourceome" for bioinformatics. Knowledge grids should be designed not only from sharing explicit knowledge on computers but also from community formulation for sharing tacit knowledge among a community. By extending the concept of grid from computing grid to knowledge grid, it is possible to make use of a grid as not only sharable computing resources, but also as time and place in which people work together, create knowledge, and share knowledge and experiences in a community.

[Harm reduction centers ("CAARUD"): privileged places for warning signal detection in addictovigilance].  

PubMed

This study aims to describe profile and consumptions of subjects suffering a substance use disorder recruited in harm reduction centers (HRC, French "CAARUD", 156 included subjects in 7 centers) for the 2010 OPPIDUM survey, performed by the French CEIP-Addictovigilance network, in order to compare them to subjects included in ambulatory care centers (ACC, French "CSAPA", 3549 subjects included in 80 centers). Subjects recruited in HRC are younger and more precarious; they consume more illicit drugs, and prescription drugs known to be diverted (methylphenidate, morphine, ketamine,…). They consume less opiate maintenance treatment, antidepressants and psychotics. Obtaining and consumption modalities are also different (more illegal acquisitions for prescription drugs, more intravenous route use and less nasal route use in HRC). HRC are privileged places for watching substance use disorder (abuse, dependence) or prescription drugs diversions, and for early warning signal detection in addictovigilance. PMID:23241253

Current Grid operation and future role of the Grid  

NASA Astrophysics Data System (ADS)

Grid-like technologies and approaches became an integral part of HEP experiments. Some other scientific communities also use similar technologies for data-intensive computations. The distinct feature of Grid computing is the ability to federate heterogeneous resources of different ownership into a seamless infrastructure, accessible via a single log-on. Like other infrastructures of similar nature, Grid functioning requires not only technologically sound basis, but also reliable operation procedures, monitoring and accounting. The two aspects, technological and operational, are closely related: weaker is the technology, more burden is on operations, and other way around. As of today, Grid technologies are still evolving: at CERN alone, every LHC experiment uses an own Grid-like system. This inevitably creates a heavy load on operations. Infrastructure maintenance, monitoring and incident response are done on several levels, from local system administrators to large international organisations, involving massive human effort worldwide. The necessity to commit substantial resources is one of the obstacles faced by smaller research communities when moving computing to the Grid. Moreover, most current Grid solutions were developed under significant influence of HEP use cases, and thus need additional effort to adapt them to other applications. Reluctance of many non-HEP researchers to use Grid negatively affects the outlook for national Grid organisations, which strive to provide multi-science services. We started from the situation where Grid organisations were fused with HEP laboratories and national HEP research programmes; we hope to move towards the world where Grid will ultimately reach the status of generic public computing and storage service provider and permanent national and international Grid infrastructures will be established. How far will we be able to advance along this path, depends on us. If no standardisation and convergence efforts will take place, Grid will become limited to HEP; if however the current multitude of Grid-like systems will converge to a generic, modular and extensible solution, Grid will become true to its name.

Power Grid Issues  

NSDL National Science Digital Library

Tampa Electric (1) offers animated illustrations that show how electricity is created and distributed. The first lets the user see the main components of a power plant, while the second outlines what is involved in transmission from the power plant to the destination. A less flashy but more detailed description of the electricity generation process is provided by the Energy Information Administration (2). This site goes more into different generation methods, such as coal, nuclear, and solar power. A few Energy Information Sheets and other resources are also available. Fuel cells are commonly discussed in terms of alternative fuel vehicles, but they might find their way into the power grid before they become standard in cars. This possibility is explored in an eight-page article (3) that highlights examples of hydrogen-powered energy systems. A similar topic is addressed in a February 2003 article in Popular Science (4). However, instead of dealing with large-scale fuel cell power plants, the article introduces fuel cells that can produce enough energy for a single family. Equipping every home with such a cell could make transmission lines obsolete, but the fact that this is currently infeasible is acknowledged. A research paper from Washington State University (5) identifies a number of risks to the power grid that could be exploited by terrorists. The authors propose specific research areas on which to focus in order to mitigate these risks, mainly dealing with communications and grid control. Related to this paper is an April 2003 article describing security measures that are being implemented to strengthen the computer systems used to operate generators and other grid components (6). The additional measures were necessary because of known weaknesses that made the systems vulnerable to intrusions. Since coal is one of the cheapest and widely available natural resources, Los Alamos National Laboratory is researching ways to make coal burning generators cleaner. The Clean Coal Technology project began several years ago, and this is one of several reports discussing a particular aspect of the project (7). The Integrated Energy and Communications System Architecture (8) is an initiative to combine the development of the power grid with advanced distributed computing technologies. The goal is to create a more efficient grid with capabilities of self-healing and intelligent management. An overview of the initiative is given on its Web site, as well as a more detailed white paper.

A fast pulse generator was designed for the grid of the injector of the electron accelerator MEA in order to shoot the electrons emitted by the cathode into the bundle pipe where they are accelerated. The generator delivers a high voltage pulse of maximum 6000 V with a rise tile smaller than 50 ns. This results in a slow rate of more than 120,000 V/microsecond. A current of 8 A is required to charge the 60 pF capacity of the grid up to 6000 V is 50 ns. The maximul pulse length is 50 microseconds with a 500 Hz pulse repetition frequency. During these 5 microseconds the pulse amplitude stability is better than 0.1 percent.

GridFTP pipelining.  

SciTech Connect

GridFTP is an exceptionally fast transfer protocol for large volumes of data. Implementations of it are widely deployed and used on well-connected Grid environments such as those of the TeraGrid because of its ability to scale to network speeds. However, when the data is partitioned into many small files instead of few large files, it suffers from lower transfer rates. The latency between the serialized transfer requests of each file directly detracts from the amount of time data pathways are active, thus lowering achieved throughput. Further, when a data pathway is inactive, the TCP window closes, and TCP must go through the slow-start algorithm. The performance penalty can be severe. This situation is known as the 'lots of small files' problem. In this paper we introduce a solution to this problem. This solution, called pipelining, allows many transfer requests to be sent to the server before any one completes. Thus, pipelining hides the latency of each transfer request by sending the requests while a data transfer is in progress. We present an implementation and performance study of the pipelining solution.

Grid alignment in entorhinal cortex.  

PubMed

The spatial responses of many of the cells recorded in all layers of rodent medial entorhinal cortex (mEC) show mutually aligned grid patterns. Recent experimental findings have shown that grids can often be better described as elliptical rather than purely circular and that, beyond the mutual alignment of their grid axes, ellipses tend to also orient their long axis along preferred directions. Are grid alignment and ellipse orientation aspects of the same phenomenon? Does the grid alignment result from single-unit mechanisms or does it require network interactions? We address these issues by refining a single-unit adaptation model of grid formation, to describe specifically the spontaneous emergence of conjunctive grid-by-head-direction cells in layers III, V, and VI of mEC. We find that tight alignment can be produced by recurrent collateral interactions, but this requires head-direction (HD) modulation. Through a competitive learning process driven by spatial inputs, grid fields then form already aligned, and with randomly distributed spatial phases. In addition, we find that the self-organization process is influenced by any anisotropy in the behavior of the simulated rat. The common grid alignment often orients along preferred running directions (RDs), as induced in a square environment. When speed anisotropy is present in exploration behavior, the shape of individual grids is distorted toward an ellipsoid arrangement. Speed anisotropy orients the long ellipse axis along the fast direction. Speed anisotropy on its own also tends to align grids, even without collaterals, but the alignment is seen to be loose. Finally, the alignment of spatial grid fields in multiple environments shows that the network expresses the same set of grid fields across environments, modulo a coherent rotation and translation. Thus, an efficient metric encoding of space may emerge through spontaneous pattern formation at the single-unit level, but it is coherent, hence context-invariant, if aided by collateral interactions.

[Neurosciences and the ravings of the Soviet era. Spanish Republican physicians, a set of privileged witnesses].  

PubMed

This study analyses the links between the Russian and Soviet neurosciences and their Spanish counterpart, especially with regard to the experiences of the Spanish Republican physicians exiled in the USSR. The Russian neurosciences, which date back to the second half of the 19th century, followed a path that ran parallel to the discipline throughout the rest of Europe and finally displayed signs of being influenced by the German and French schools. Important figures include Alexei Kojevnikov and Vladimir Bekhterev in neurology, Sergei Korsakov in psychiatry, Ivan Pavlov and his disciple Piotr Anojin in neurophysiology, Lev Vygotsky and Alexander Luria in neuropsychology, and Nikolai Burdenko in neurosurgery. When the Bolsheviks came to power, they brought with them a progressive conception of health care, which was modified during the Stalinist era to serve political interests, above all in the case of psychiatry. During the first third of the 20th century, Spanish scientists became interested in Pavlov's reflexology and the Soviets took a similar interest in Spanish histology. Among the 4500 Spanish Republicans who emigrated to the USSR because of the Spanish Civil War, there were several dozen physicians who were privileged witnesses of the madness that shook the science and the health care of that period. Relevant names worth citing here from the field of the neurosciences include Juan Planelles and Ramon Alvarez-Buylla in neurophysiology, Federico Pascual and Florencio Villa Landa in psychiatry, Angel Escobio and Maria Perez in neurology, Julian Fuster in neurosurgery and Manuel Arce in neuroimaging.

Postmodern research: no grounding or privilege, just free-floating trouble making.  

PubMed

Postmodernism has been criticized as failing to offer, on the one hand, authoritative explanations for social phenomena that might provide a scientific basis for policy formation or, on the other, the philosophical justification for emancipatory work-its radical scepticism about claims to knowledge leaving its advocates, including many nurses, with little scope to transform oppressive social and political regimes. Various approaches to this important problem have been offered, both philosophical and methodological. Some critical theorists have rejected certain aspects of postmodernism as dangerous and distracting. Some more accommodating solutions are troubled by unacknowledged inconsistencies. Others embrace postmodernism's unavoidable ambiguity (towards the Enlightenment for instance) with a lighter heart. In this paper I will review some of the criticism of postmodernism and some proposed solutions to these problems. Using recent research into the impact of managerialism on nursing within the UK National Health Service as an example and drawing on deconstructive literary theory, I conclude by accepting a rhetorical agonistics of undecidability. I take postmodernism as a mandate for causing trouble for those groups who are currently having their say and whose version of truth and rationality has achieved domination over others. I do not take postmodernism as a place from which to champion the cause or privilege the view of any particular group. PMID:9224046

Expression and distribution of immunoglobulin G and its receptors in an immune privileged site: the eye.  

PubMed

It has recently been demonstrated that not only mature B lymphocytes, but also non-lymphoid cells, including cancer cells and neurons, express IgG. In the eye, an important immune privileged site, the presence of IgG has been ascribed to IgG entering the eye through breaches of the blood–ocular barrier. Here we demonstrate that the eye itself can produce IgG intrinsically. Applying immunohistochemistry, in situ hybridization, and RT-PCR, several intraocular structures were found to express proteins and mRNA transcripts of IgG heavy chains, light chains, V(D)J rearrangements, and enzymes required for V(D)J recombination. IgG receptors were also detected in the intraocular epithelium and endothelium. The extensive distribution of IgG and its receptors in intraocular structures indicates that locally produced IgG could play a significant role in maintaining the ocular microenvironment and protection of the eyes, and it might also be involved in the pathogenesis of age-related macular degeneration and some inflammatory diseases.

Explaining and inducing savant skills: privileged access to lower level, less-processed information.  

PubMed

I argue that savant skills are latent in us all. My hypothesis is that savants have privileged access to lower level, less-processed information, before it is packaged into holistic concepts and meaningful labels. Owing to a failure in top-down inhibition, they can tap into information that exists in all of our brains, but is normally beyond conscious awareness. This suggests why savant skills might arise spontaneously in otherwise normal people, and why such skills might be artificially induced by low-frequency repetitive transcranial magnetic stimulation. It also suggests why autistic savants are atypically literal with a tendency to concentrate more on the parts than on the whole and why this offers advantages for particular classes of problem solving, such as those that necessitate breaking cognitive mindsets. A strategy of building from the parts to the whole could form the basis for the so-called autistic genius. Unlike the healthy mind, which has inbuilt expectations of the world (internal order), the autistic mind must simplify the world by adopting strict routines (external order). PMID:19528023

Privileged visual processing of the straight-ahead direction in humans.  

PubMed

At any moment, the objects we face are endowed with a special behavioral status, either as potential obstacles during navigation or as optimal targets for visually guided actions. Yet, the gaze frequently jumps from one location to another when exploring the visual surroundings, so that objects located straight-ahead are often seen from the corner of the eyes. In the present study, we tested the hypothesis that peripheral vision might nevertheless ensure a privileged processing of these behaviorally important objects. Human subjects were asked to respond as fast as possible to the appearance of visual objects in their peripheral field of view while gazing successively in different directions. The visual objects formed similar images on the retina and differed only with respect to their egocentric location: either straight-ahead or eccentric with respect to the head/body midline. We found that straight-ahead objects elicit consistently shorter behavioral responses than eccentric objects (median difference of at least 10 ms). Additional experiments indicate that neither binocular visual cues nor full attentional resources play a fundamental role in this mechanism, and that it cannot be resumed to a simple preference for objects contralateral to the direction of gaze. These results are in agreement with recent electrophysiological findings showing that the early integration of gaze-related signals in the visual cortex of macaque monkeys lead to a higher neuronal sensitivity to the straight-ahead direction.

Privilege, power, and public health programs: a student perspective on deconstructing institutional racism in community service learning.  

PubMed

The Association of Schools of Public Health has identified "diversity and culture" as 1 of 7 crosscutting competencies that public health students are expected to achieve. This competency is traditionally incorporated into the curriculum through a community service-learning (CSL) component that aims to expose students to racial/ethnic health disparities. However, this model of CSL is problematic because although students are directly engaging with community members, it does not ensure long-term sustainable changes or benefits for the host community. Moreover, academic institutions have developed significant critiques of traditional CSL models where white middle-class students engage with low-income clients and communities of color, potentially reinforcing Eurocentric power and privilege. As such, public health programs require a shift in both pedagogy and curricula that more directly addresses underlying institutional racism in health disparities. Consistent with the principles of public health, a social justice framework is imperative in teaching cultural competency and should facilitate discussion of racial injustice and privilege in the students' own lives. This brief presents an autobiographical personal narrative of my experiences with CSL as a racial/ethnic minority student in a California graduate school of public health. Although autoethnography is inherently limited, this brief highlights my observations of the limitations of the service-learning model to adequately educate students on the intersection of racism and health outcomes. In addition, the brief includes suggestions for creating inclusive curricula that critically examine issues of privilege, oppression, and power dynamics related to race/ethnicity. PMID:21617417

Galectin-9-Mediated Protection from Allo-Specific T Cells as a Mechanism of Immune Privilege of Corneal Allografts  

PubMed Central

The eye is an immune-privileged organ, and corneal transplantation is therefore one of the most successful organ transplantation. The immunosuppressive intraocular microenvironment is known as one of the mechanisms underlying immune privilege in the eye. T-cell immunoglobulin and mucin domain (Tim)-3 is a regulatory molecule for T-cell function, and galectin (Gal)-9 is a Tim-3 ligand. We investigated the role of this pathway in establishing the immune-privileged status of corneal allografts in mice. Gal-9 is constitutively expressed on the corneal epithelium, endothelium and iris-ciliary body in normal mouse eyes and eyes bearing surviving allografts, and Tim-3 was expressed on CD8 T cells infiltrating the allografts. Allograft survival in recipients treated with anti-Tim-3 monoclonal antibody (mAb) or anti-Gal-9 mAb was significantly shorter than that in control recipients. In vitro, destruction of corneal endothelial cells by allo-reactive T cells was enhanced when the cornea was pretreated with anti-Gal-9 mAb. Blockade of Tim-3 or Gal-9 did not abolish anterior chamber-associated immune deviation. We propose that constitutive expression of Gal-9 plays an immunosuppressive role in corneal allografts. Gal-9 expressed on corneal endothelial cells protects them from destruction by allo-reactive T cells within the cornea.

Grid-Enabled Measures  

PubMed Central

Scientists are taking advantage of the Internet and collaborative web technology to accelerate discovery in a massively connected, participative environment —a phenomenon referred to by some as Science 2.0. As a new way of doing science, this phenomenon has the potential to push science forward in a more efficient manner than was previously possible. The Grid-Enabled Measures (GEM) database has been conceptualized as an instantiation of Science 2.0 principles by the National Cancer Institute with two overarching goals: (1) Promote the use of standardized measures, which are tied to theoretically based constructs; and (2) Facilitate the ability to share harmonized data resulting from the use of standardized measures. This is done by creating an online venue connected to the Cancer Biomedical Informatics Grid (caBIG®) where a virtual community of researchers can collaborate together and come to consensus on measures by rating, commenting and viewing meta-data about the measures and associated constructs. This paper will describe the web 2.0 principles on which the GEM database is based, describe its functionality, and discuss some of the important issues involved with creating the GEM database, such as the role of mutually agreed-on ontologies (i.e., knowledge categories and the relationships among these categories— for data sharing).

Deployment of the CMS software on the WLCG Grid  

NASA Astrophysics Data System (ADS)

The CMS Experiment is taking high energy collision data at CERN. The computing infrastructure used to analyse the data is distributed round the world in a tiered structure. In order to use the 7 Tier-1 sites, the 50 Tier-2 sites and a still growing number of about 30 Tier-3 sites, the CMS software has to be available at those sites. Except for a very few sites the deployment and the removal of CMS software is managed centrally. Since the deployment team has no local accounts at the remote sites all installation jobs have to be sent via Grid jobs. Via a VOMS role the job has a high priority in the batch system and gains write privileges to the software area. Due to the lack of interactive access the installation jobs must be very robust against possible failures, in order not to leave a broken software installation. The CMS software is packaged in RPMs that are installed in the software area independent of the host OS. The apt-get tool is used to resolve package dependencies. This paper reports about the recent deployment experiences and the achieved performance.

A Java commodity grid kit.  

SciTech Connect

In this paper we report on the features of the Java Commodity Grid Kit. The Java CoG Kit provides middleware for accessing Grid functionality from the Java framework. Java CoG Kit middleware is general enough to design a variety of advanced Grid applications with quite different user requirements. Access to the Grid is established via Globus protocols, allowing the Java CoG Kit to communicate also with the C Globus reference implementation. Thus, the Java CoG Kit provides Grid developers with the ability to utilize the Grid, as well as numerous additional libraries and frameworks developed by the Java community to enable network, Internet, enterprise, and peer-to peer computing. A variety of projects have successfully used the client libraries of the Java CoG Kit to access Grids driven by the C Globus software. In this paper we also report on the efforts to develop server side Java CoG Kit components. As part of this research we have implemented a prototype pure Java resource management system that enables one to run Globus jobs on platforms on which a Java virtual machine is supported, including Windows NT machines.

Breakdown of immune privilege and spontaneous autoimmunity in mice expressing a transgenic T cell receptor specific for a retinal autoantigen.  

PubMed

Despite presence of circulating retina-specific T cells in healthy individuals, ocular immune privilege usually averts development of autoimmune uveitis. To study the breakdown of immune privilege and development of disease, we generated transgenic (Tg) mice that express a T cell receptor (TCR) specific for interphotoreceptor retinoid-binding protein (IRBP), which serves as an autoimmune target in uveitis induced by immunization. Three lines of TCR Tg mice, with different levels of expression of the transgenic R161 TCR and different proportions of IRBP-specific CD4? T cells in their peripheral repertoire, were successfully established. Importantly, two of the lines rapidly developed spontaneous uveitis, reaching 100% incidence by 2 and 3 months of age, respectively, whereas the third appeared "poised" and only developed appreciable disease upon immune perturbation. Susceptibility roughly paralleled expression of the R161 TCR. In all three lines, peripheral CD4? T cells displayed a naïve phenotype, but proliferated in vitro in response to IRBP and elicited uveitis upon adoptive transfer. In contrast, CD4? T cells infiltrating uveitic eyes mostly showed an effector/memory phenotype, and included Th1, Th17 as well as T regulatory cells that appeared to have been peripherally converted from conventional CD4? T cells rather than thymically derived. Thus, R161 mice provide a new and valuable model of spontaneous autoimmune disease that circumvents the limitations of active immunization and adjuvants, and allows to study basic mechanisms involved in maintenance and breakdown of immune homeostasis affecting immunologically privileged sites such as the eye.

Lichen planopilaris is characterized by immune privilege collapse of the hair follicle's epithelial stem cell niche.  

PubMed

Lichen planopilaris (LPP) is a chronic inflammatory disease of unknown pathogenesis that leads to permanent hair loss. Whilst destruction of epithelial hair follicle stem cells (eHFSCs) that reside in an immunologically protected niche of the HF epithelium, the bulge, is a likely key event in LPP pathogenesis, this remains to be demonstrated. We have tested the hypotheses that bulge immune privilege (IP) collapse and inflammation-induced eHFSC death are key components in the pathogenesis of LPP. Biopsies of lesional and non-lesional scalp skin from adult LPP patients (n = 42) were analysed by quantitative (immuno)histomorphometry, real-time quantitative polymerase chain reaction (qRT-PCR), laser capture microdissection and microarray analysis, or skin organ culture. At both the protein and transcriptional level, lesional LPP HFs showed evidence for bulge IP collapse (ie increased expression of MHC class I and II, ?2microglobulin; reduced TGF?2 and CD200 expression). This was accompanied by a Th1-biased cytotoxic T cell response (ie increased CD8(+) GranzymeB(+) T cells and CD123(+) plasmacytoid dendritic cells, with increased CXCR3 expression) and increased expression of interferon-inducible chemokines (CXCL9/10/11). Interestingly, lesional LPP eHFSCs showed both increased proliferation and apoptosis in situ. Microarray analysis revealed a loss of eHFSC signatures and increased expression of T cell activation/binding markers in active LPP, while bulge PPAR? transcription was unaltered compared to non-lesional LPP HFs. In organ culture of non-lesional LPP skin, interferon-? (IFN?) induced bulge IP collapse. LPP is an excellent model disease for studying and preventing immune destruction of human epithelial stem cells in situ. These novel findings raise the possibility that LPP represents an autoimmune disease in whose pathogenesis IFN?-induced bulge IP collapse plays an important role. Therapeutically, bulge IP protection/restoration may help to better manage this highly treatment-resistant cicatricial alopecia. Copyright © 2013 Pathological Society of Great Britain and Ireland.

National Smart Water Grid  

SciTech Connect

The United States repeatedly experiences floods along the Midwest's large rivers and droughts in the arid Western States that cause traumatic environmental conditions with huge economic impact. With an integrated approach and solution these problems can be alleviated. Tapping into the Mississippi River and its tributaries, the world's third largest fresh water river system, during flood events will mitigate the damage of flooding and provide a new source of fresh water to the Western States. The trend of increased flooding on the Midwest's large rivers is supported by a growing body of scientific literature. The Colorado River Basin and the western states are experiencing a protracted multi-year drought. Fresh water can be pumped via pipelines from areas of overabundance/flood to areas of drought or high demand. Calculations document 10 to 60 million acre-feet (maf) of fresh water per flood event can be captured from the Midwest's Rivers and pumped via pipelines to the Colorado River and introduced upstream of Lake Powell, Utah, to destinations near Denver, Colorado, and used in areas along the pipelines. Water users of the Colorado River include the cities in southern Nevada, southern California, northern Arizona, Colorado, Utah, Indian Tribes, and Mexico. The proposed start and end points, and routes of the pipelines are documented, including information on right-of-ways necessary for state and federal permits. A National Smart Water Grid{trademark} (NSWG) Project will create thousands of new jobs for construction, operation, and maintenance and save billions in drought and flood damage reparations tax dollars. The socio-economic benefits of NWSG include decreased flooding in the Midwest; increased agriculture, and recreation and tourism; improved national security, transportation, and fishery and wildlife habitats; mitigated regional climate change and global warming such as increased carbon capture; decreased salinity in Colorado River water crossing the US-Mexico border; and decreased eutrophication (excessive plant growth and decay) in the Gulf of Mexico to name a few. The National Smart Water Grid{trademark} will pay for itself in a single major flood event.

Towards Smart Grid Dynamic Ratings  

NASA Astrophysics Data System (ADS)

The energy distribution industry is giving greater attention to smart grid solutions as a means for increasing the capabilities, efficiency and reliability of the electrical power network. The smart grid makes use of intelligent monitoring and control devices throughout the distribution network to report on electrical properties such as voltage, current and power, as well as raising network alarms and events. A further aspect of the smart grid embodies the dynamic rating of electrical assets of the network. This fundamentally involves a rating of the load current capacity of electrical assets including feeders, transformers and switches. The mainstream approach to rate assets is to apply the vendor plate rating, which often under utilizes assets, or in some cases over utilizes when environmental conditions reduce the effective rated capacity, potentially reducing lifetime. Using active intelligence we have developed a rating system that rates assets in real time based upon several events. This allows for a far more efficient and reliable electrical grid that is able to extend further the life and reliability of the electrical network. In this paper we describe our architecture, the observations made during development and live deployment of the solution into operation. We also illustrate how this solution blends with the smart grid by proposing a dynamic rating system for the smart grid.

Most Grids deployed at large scale are production platforms that are inappropriate research tools because of their limited reconfiguration, control and monitoring capabilities. In this paper, we present Grid'5000, a 5000 CPU nation-wide infrastructure for research in Grid computing. Grid'5000 is designed to

Numerical simulation of gridded electrostatic lens.  

PubMed

Gridded electrostatic lenses are frequently used in extraction systems and low energy ion beam transport line. Typically, for numerical simulation the grid is treated as a metal plate transparent for beam particles. The influence of real grid geometry on the beam dynamics in the gridded lens has been investigated by KOBRA-3d code. Beam emittance growth for different lens parameters has been investigated. Approximating expressions for obtained results are presented. The grid geometry providing minimal beam distortions is proposed. PMID:22380339

Grid-based Visualization Framework  

NASA Astrophysics Data System (ADS)

Advances in science and engineering have put high demands on tools for high-performance large-scale visual data exploration and analysis. For example, earthquake scientists can now study earthquake phenomena from first principle physics-based simulations. These simulations can generate large amounts of data, possibly high spatial resolution, and long time series. Single-system visualization software running on commodity machines cannot scale up to the large amounts of data generated by these simulations. To address this problem, we propose a flexible and extensible Grid-based visualization framework for time-critical, interactively controlled visual browsing of spatially and temporally large datasets in a Grid environment. Our framework leverages Grid resources for scalable computation and data storage to maintain performance and interactivity with large visualization jobs. Our framework utilizes Globus Toolkit 2.4 components for security (i.e., GSI), resource allocation and management (i.e., DUROC, GRAM) and communication (i.e., Globus-IO) to couple commodity desktops with remote, scalable storage and computational resources in a Grid for interactive data exploration. There are two major components in this framework---Grid Data Transport (GDT) and the Grid Visualization Utility (GVU). GDT provides libraries for performing parallel data filtering and parallel data exchange among Grid resources. GDT allows arbitrary data filtering to be integrated into the system. It also facilitates multi-tiered pipeline topology construction of compute resources and displays. In addition to scientific visualization applications, GDT can be used to support other applications that require parallel processing and parallel transfer of partial ordered independent files, such as file-set transfer. On top of GDT, we have developed the Grid Visualization Utility (GVU), which is designed to assist visualization dataset management, including file formatting, data transport and automatic byte swapping. GVU also supports parameterized data reduction filters such as point sampling with scalar range culling, as well as volume cropping, and down sampling. The GVU framework can be used to facilitate the parallel execution of existing transformation filters, such as the VTK marching cubes iso-surface filter, as well as other custom domain-specific filters. Our initial implementation supports remote synthesis of view point independent display lists. This feature allows the local display machine to control the view point for reduced view point latency, and multi-view rendering (e.g., stereo rendering). The poster will provide an architectural design of the Grid-based visualization framework and its components. We will also show a brief demo/movie of our work, and how it is being used to visualize 4D earthquake wave propagation data.

ASCI Grid Services summary report.  

SciTech Connect

The ASCI Grid Services (initially called Distributed Resource Management) project was started under DisCom{sup 2} when distant and distributed computing was identified as a technology critical to the success of the ASCI Program. The goals of the Grid Services project has and continues to be to provide easy, consistent access to all the ASCI hardware and software resources across the nuclear weapons complex using computational grid technologies, increase the usability of ASCI hardware and software resources by providing interfaces for resource monitoring, job submission, job monitoring, and job control, and enable the effective use of high-end computing capability through complex-wide resource scheduling and brokering. In order to increase acceptance of the new technology, the goal included providing these services in both the unclassified as well as the classified user's environment. This paper summarizes the many accomplishments and lessons learned over approximately five years of the ASCI Grid Services Project. It also provides suggestions on how to renew/restart the effort for grid services capability when the situation is right for that need.

Heliospheric Modeling on Geodesic Grids  

NASA Astrophysics Data System (ADS)

We present a new space plasma modeling framework based on a hexagonal spherical geodesic grid, comprised of an MHD plasma multiple fluid solver and a cosmic-ray kinetic transport solver. This report focuses on the MHD component designed to simulate flows of partially ionized plasmas in and around the Sun's heliosphere. A geodesic grid is an example of a uniform spherical tiling produced by a recursive division of a base icosahedron. The main benefit of the uniform solid angle coverage over spherical polar grids is the reduced restriction on the global time step, improving computational performance of both components of the code. Two simple MHD calculations, a time-dependent evolution of corotating interaction regions and a simulation of the large-scale structure of the heliosphere, are discussed.

Two plates are provided with intersecting unequally spaced slots that define polygons on one side of each plate. Both plates have bores therethrough substantially at the slot intersections and in the slots adjacent the outer edges of the plates. Bores are provided through both plates in polygons that correspond to fuel assembly guide tube and instrument tube locations. These positions receive guide cell pins during use, some of which are hollow and are used to bolt the plates together over the spacer grid strips. Bores in each plate through the defined polygons receive alignment pins. Guide rods receive and align the plates through corner bores in each plate. The slots and pins in the facing plates align the critical fuel rod contact points in the spacer grid during the intersection welding process. 19 figs.

Grid Integration of Wind Farms  

NASA Astrophysics Data System (ADS)

This article gives an overview of grid integration of wind farms with respect to impact on voltage quality and power system stability. The recommended procedure for assessing the impact of wind turbines on voltage quality in distribution grids is presented. The procedure uses the power quality characteristic data of wind turbines to determine the impact on slow voltage variations, flicker, voltage dips and harmonics. The detailed assessment allows for substantially more wind power in distribution grids compared with previously used rule-of-thumb guidelines. Power system stability is a concern in conjunction with large wind farms or very weak grids. Assessment requires the use of power system simulation tools, and wind farm models for inclusion in such tools are presently being developed. A fixed-speed wind turbine model is described. The model may be considered a good starting point for development of more advanced models, hereunder the concept of variable-speed wind turbines with a doubly fed induction generator is briefly explained. The use of dynamic wind farm models as part of power system simulation tools allows for detailed studies and development of innovative grid integration techniques. It is demonstrated that the use of reactive compensation may relax the short-term voltage stability limit and allow integration of significantly more wind power, and that application of automatic generation control technology may be an efficient means to circumvent thermal transmission capacity constraints. The continuous development of analysis tools and technology for cost-effective and secure grid integration is an important aid to ensure the increasing use of wind energy. A key factor for success, however, is the communication of results and gained experience, and in this regard it is hoped that this article may contribute.

Convectively cooled electrical grid structure  

DOEpatents

Undesirable distortions of electrical grid conductors from thermal cycling are minimized and related problems such as unwanted thermionic emission and structural failure from overheating are avoided by providing for a flow of fluid coolant within each conductor. The conductors are secured at each end to separate flexible support elements which accommodate to individual longitudinal expansion and contraction of each conductor while resisting lateral displacements, the coolant flow preferably being directed into and out of each conductor through passages in the flexible support elements. The grid may have a modular or divided construction which facilitates manufacture and repairs.

Behind the scenes of a research and training collaboration: power, privilege, and the hidden transcript of race.  

PubMed

This paper examines a federally funded research and training collaboration between an Ivy League psychiatric research center and a historically Black university and medical center. This collaboration focuses on issues of psychiatric recovery and rehabilitation among African Americans. In addition, this multidisciplinary collaboration aims to build the research capacity at both institutions and to contribute to the tradition of research in culture and mental health within the medical social sciences and cultural psychiatry. This article provides a window into the complex, often messy, dynamics of a collaboration that cross cuts institutional, disciplinary, and demographic boundaries. Taking an auto-ethnographic approach, we intend to illustrate how collaborative relationships unfold and are constructed through ongoing reciprocal flows of knowledge and experience. Central to this aim is a consideration of how issues of power, privilege, and the hidden transcript of race shape the nature of our research and training efforts. PMID:23580139

Cognitive load privileges memory-based over data-driven processing, not group-level over person-level processing.  

PubMed

In the current paper, we argue that categorization and individuation, as traditionally discussed and as experimentally operationalized, are defined in terms of two confounded underlying dimensions: a person/group dimension and a memory-based/data-driven dimension. In a series of three experiments, we unconfound these dimensions and impose a cognitive load. Across the three experiments, two with laboratory-created targets and one with participants' friends as the target, we demonstrate that cognitive load privileges memory-based over data-driven processing, not group- over person-level processing. We discuss the results in terms of their implications for conceptualizations of the categorization/individuation distinction, for the equivalence of person and group processes, for the ultimate 'purpose' and meaningfulness of group-based perception and, fundamentally, for the process of categorization, broadly defined.

The Privileging of Communitarian Ideas: Citation Practices and the Translation of Social Capital Into Public Health Research  

PubMed Central

The growing use of social science constructs in public health invites reflection on how public health researchers translate, that is, appropriate and reshape, constructs from the social sciences. To assess how 1 recently popular construct has been translated into public health research, we conducted a citation network and content analysis of public health articles on the topic of social capital. The analyses document empirically how public health researchers have privileged communitarian definitions of social capital and marginalized network definitions in their citation practices. Such practices limit the way public health researchers measure social capital’s effects on health. The application of social science constructs requires that public health scholars be sensitive to how their own citation habits shape research and knowledge.

FasL Expression on Human Nucleus Pulposus Cells Contributes to the Immune Privilege of Intervertebral Disc by Interacting with Immunocytes  

PubMed Central

The mechanisms of immune privilege in human nucleus pulposus (NP) remain unclear. Accumulating evidence indicates that Fas ligand (FasL) might play an important role in the immune privilege of the disc. We aimed for addressing the role of FasL expression in human intervertebral disc degeneration (IDD) and immune privilege in terms of the interaction between NP cells and immunocytes via the FasL-Fas machinery. We collected NP specimens from 20 patients with IDD as degenerative group and 8 normal cadaveric donors as control. FasL expression was detected by qRT-PCR, western blotting and flow cytometry (FCM). We also collected macrophages and CD8+ T cells from the peripheral blood of patients with IDD for co-cultures with NP cells. And macrophages and CD8+ T cells were harvested for apoptosis analysis by FCM after 2 days of co-cultures. We found that FasL expression in mRNA, protein and cellular resolutions demonstrated a significant decrease in degenerative group compared with normal control (p<0.05). FCM analysis found that human NP cells with increased FasL expression resulted in significantly increased apoptosis ratio of macrophages and CD8+ T cells. Our study demonstrated that FasL expression tends to decrease in degenerated discs and FasL plays an important role in human disc immune privilege, which might provide a novel target for the treatment strategies for IDD.

Grid Logging: Best Practices Guide  

SciTech Connect

The purpose of this document is to help developers of Grid middleware and application software generate log files that will be useful to Grid administrators, users, developers and Grid middleware itself. Currently, most of the currently generated log files are only useful to the author of the program. Good logging practices are instrumental to performance analysis, problem diagnosis, and security auditing tasks such as incident tracing and damage assessment. This document does not discuss the issue of a logging API. It is assumed that a standard log API such as syslog (C), log4j (Java), or logger (Python) is being used. Other custom logging API or even printf could be used. The key point is that the logs must contain the required information in the required format. At a high level of abstraction, the best practices for Grid logging are: (1) Consistently structured, typed, log events; (2) A standard high-resolution timestamp; (3) Use of logging levels and categories to separate logs by detail and purpose; (4) Consistent use of global and local identifiers; and (5) Use of some regular, newline-delimited ASCII text format. The rest of this document describes each of these recommendations in detail.

Grid computing in image analysis.

Diagnostic surgical pathology or tissue–based diagnosis still remains the most reliable and specific diagnostic medical procedure. The development of whole slide scanners permits the creation of virtual slides and to work on so-called virtual microscopes. In addition to interactive work on virtual slides approaches have been reported that introduce automated virtual microscopy, which is composed of several tools focusing on quite different tasks. These include evaluation of image quality and image standardization, analysis of potential useful thresholds for object detection and identification (segmentation), dynamic segmentation procedures, adjustable magnification to optimize feature extraction, and texture analysis including image transformation and evaluation of elementary primitives. Grid technology seems to possess all features to efficiently target and control the specific tasks of image information and detection in order to obtain a detailed and accurate diagnosis. Grid technology is based upon so-called nodes that are linked together and share certain communication rules in using open standards. Their number and functionality can vary according to the needs of a specific user at a given point in time. When implementing automated virtual microscopy with Grid technology, all of the five different Grid functions have to be taken into account, namely 1) computation services, 2) data services, 3) application services, 4) information services, and 5) knowledge services. Although all mandatory tools of automated virtual microscopy can be implemented in a closed or standardized open system, Grid technology offers a new dimension to acquire, detect, classify, and distribute medical image information, and to assure quality in tissue–based diagnosis.

Although all mandatory tools of automated virtual microscopy can be implemented in a closed or standardized open system, Grid technology offers a new dimension to acquire, detect, classify, and distribute medical image information, and to assure quality in tissue–based diagnosis.

Lattice boltzmann method on composite grids  

PubMed

A composite block-structured lattice Boltzmann method is proposed for the simulation of two-dimensional incompressible fluid flows. The grid structure is composed of a coarse base grid and one or several fine grid(s). The former covers the entire physical domain; the latter are placed at regions where local grid refinement is desirable. The simulation is first carried out on the base grid level at a smaller relaxation time, allowing a rapid propagation of boundary information throughout the entire domain. Thus large-scale flow features can be resolved efficiently at a relatively low cost. At a later time, fine grid variables are initiated. The dependent variables on both grid levels are, then, advanced in time simultaneously with the fine grid boundary conditions obtained from the base grid solution at the grid interface. As a demonstration, the lid-driven cavity flow is selected for study. The results show good agreement with benchmark numerical data and those calculated from the finite-volume U2RANS model. The proposed method is able to produce accurate solutions on fine grids, with a considerable saving in CPU time. PMID:11088688

Solving Partial Differential Equations on Overlapping Grids  

SciTech Connect

We discuss the solution of partial differential equations (PDEs) on overlapping grids. This is a powerful technique for efficiently solving problems in complex, possibly moving, geometry. An overlapping grid consists of a set of structured grids that overlap and cover the computational domain. By allowing the grids to overlap, grids for complex geometries can be more easily constructed. The overlapping grid approach can also be used to remove coordinate singularities by, for example, covering a sphere with two or more patches. We describe the application of the overlapping grid approach to a variety of different problems. These include the solution of incompressible fluid flows with moving and deforming geometry, the solution of high-speed compressible reactive flow with rigid bodies using adaptive mesh refinement (AMR), and the solution of the time-domain Maxwell's equations of electromagnetism.

Smart Grid Interoperability Maturity Model  

SciTech Connect

The integration of automation associated with electricity resources (including transmission and distribution automation and demand-side resources operated by end-users) is key to supporting greater efficiencies and incorporating variable renewable resources and electric vehicles into the power system. The integration problems faced by this community are analogous to those faced in the health industry, emergency services, and other complex communities with many stakeholders. To highlight this issue and encourage communication and the development of a smart grid interoperability community, the GridWise Architecture Council (GWAC) created an Interoperability Context-Setting Framework. This "conceptual model" has been helpful to explain the importance of organizational alignment in addition to technical and informational interface specifications for "smart grid" devices and systems. As a next step to building a community sensitive to interoperability, the GWAC is investigating an interoperability maturity model (IMM) based on work done by others to address similar circumstances. The objective is to create a tool or set of tools that encourages a culture of interoperability in this emerging community. The tools would measure status and progress, analyze gaps, and prioritize efforts to improve the situation.

Telemedical applications and grid technology  

NASA Astrophysics Data System (ADS)

Due to the experience in the exploitation of previous European telemedicine projects an open Euro-Mediterranean consortium proposes the Virtual Euro-Mediterranean Hospital (VEMH) initiative. The provision of the same advanced technologies to the European and Mediterranean Countries should contribute to their better dialogue for integration. VEMH aims to facilitate the interconnection of various services through real integration which must take into account the social, human and cultural dimensions. VEMH will provide a platform consisting of a satellite and terrestrial link for the application of medical e-learning, real-time telemedicine and medical assistance. The methodologies for the VEMH are medical-needs-driven instead of technology-driven. They supply new management tools for virtual medical communities and allow management of clinical outcomes for implementation of evidence-based medicine. Due to the distributed character of the VEMH Grid technology becomes inevitable for successful deployment of the services. Existing Grid Engines provide basic computing power needed by today's medical analysis tasks but lack other capabilities needed for communication and knowledge sharing services envisioned. When it comes to heterogeneous systems to be shared by different institutions especially the high level system management areas are still unsupported. Therefore a Metagrid Engine is needed that provides a superset of functionalities across different Grid Engines and manages strong privacy and Quality of Service constraints at this comprehensive level.

DIGRD: an interactive grid generating program  

SciTech Connect

Pacific Northwest Laboratory has completed the development and documentation of an interactive grid generating program (DIGRD, digitize grid). This program is designed to rapidly generate or modify grids necessary for the unsaturated flow code TRUST. In addition to the code, a user's manual was prepared. Unfortunately, the computer hardware that comprises the PNL interactive graphics capability is unique. Direct technology transfer is not possible, therefore, this report is intended to convey the utility of interactive graphics in supplying a grid generating capability. DIGRD has already been effectively used in the preparation of grids for the analysis of leachate movement from uranium mill tailings. The principal conclusion is that the interactive graphics employed in DIGRD are useful and economical in the development of complex grids. Grid generation activities that previously took between a half- and a full-man month can now be completed in less than a week. DIGRD users have recommended development of an uniform grid of either rectangles or equilateral triangles, which could be superimposed on any domain and then adjusted through the DIGRD program to match the boundaries of a tailings disposal facility. This improvement to the DIGRD package could further reduce the effort in grid generation while providing more optimal grids.

Earlier work suggested that the immunologically privileged site of the rat testis was associated with anomalous testicular lymph drainage whereby some lymphatic trunks bypassed regional lymph nodes and opened directly into the systemic blood circulation via the cisterna chyli and thoracic duct. Because other workers also noted the privileged status of the testes in untreated mice and guinea pigs, we opted to examine the nature of the testicular extrinsic lymphatic system in these rodents using the rat model for comparison. Contrary to expectation, there were no direct lymphatic-venous communications draining the testes of either guinea pigs or mice. Instead, testicular lymphatics drained into at least one lymph node before reaching the blood circulation. This disparity from testicular lymphatic drainage of the rat suggests that the immunologic privilege, if any, in mice and guinea pigs has an alternative explanation (e.g., lymphatic effect of steroidal factors emanating from the testicles or adrenal gland and altering the response to foreign graft).

Grid generation for a pump collector  

NASA Astrophysics Data System (ADS)

A simple scheme is presented which generates a surface-fitted grid for a pump collector with application to numerical solution of frozen vorticity flow inside the collector (the application to be covered in a later report). The scheme is two-dimensional in nature, but by a simplification of the collector geometry generates a three-dimensional grid. The procedure is very fast, requiring between two and three seconds of CPU time on an IBM 370/3033. Example grids are presented for several collector geometries. To develop a capability for computing such a grid would require considerable time and effort. The development time can be reduced drastically by making two simplifying assumptions about the collector geometry. Thus, a two-dimensional grid can be fitted to the cross sections of the simplified geometry and then rotated about the O axis to produce a three-dimensional grid.

Interpolation on spherical geodesic grids  

NASA Astrophysics Data System (ADS)

Most operational models in atmospheric physics, meteorology and climatology nowadays adopt spherical geodesic grids and require "ad hoc" developed interpolation procedures. The author does a comparison between chosen representatives of linear, distance-based and cubic interpolation schemes outlining their advantages and drawbacks in this specific application field. Numerical experiments on a standard test problem, while confirming a good performance of linear and distance-based schemes in a single interpolation step, also show their minor accuracy with respect to the cubic scheme in the more realistic simulation of advection of a meteorological field.

Grid computing and biomolecular simulation.  

PubMed

Biomolecular computer simulations are now widely used not only in an academic setting to understand the fundamental role of molecular dynamics on biological function, but also in the industrial context to assist in drug design. In this paper, two applications of Grid computing to this area will be outlined. The first, involving the coupling of distributed computing resources to dedicated Beowulf clusters, is targeted at simulating protein conformational change using the Replica Exchange methodology. In the second, the rationale and design of a database of biomolecular simulation trajectories is described. Both applications illustrate the increasingly important role modern computational methods are playing in the life sciences. PMID:16099764

Insightful Workflow For Grid Computing  

SciTech Connect

We developed a workflow adaptation and scheduling system for Grid workflow. The system currently interfaces with and uses the Karajan workflow system. We developed machine learning agents that provide the planner/scheduler with information needed to make decisions about when and how to replan. The Kubrick restructures workflow at runtime, making it unique among workflow scheduling systems. The existing Kubrick system provides a platform on which to integrate additional quality of service constraints and in which to explore the use of an ensemble of scheduling and planning algorithms. This will be the principle thrust of our Phase II work.

Bag-of-Tasks applications (those parallel applications whose tasks are independent) are both relevant and amendable for execution on com- putational grids. In fact, one can argue that Bag-of-Tasks applications are the applications most suited for grids, where communication can easily become a bottleneck for tightly-coupled parallel applications. In spite of such suitability, few users currently execute their Bag-of-Tasks applications on grids.

Ion mobility spectrometer with virtual aperture grid  

DOEpatents

An ion mobility spectrometer does not require a physical aperture grid to prevent premature ion detector response. The last electrodes adjacent to the ion collector (typically the last four or five) have an electrode pitch that is less than the width of the ion swarm and each of the adjacent electrodes is connected to a source of free charge, thereby providing a virtual aperture grid at the end of the drift region that shields the ion collector from the mirror current of the approaching ion swarm. The virtual aperture grid is less complex in assembly and function and is less sensitive to vibrations than the physical aperture grid.

Grid computing in large pharmaceutical molecular modeling.  

PubMed

Most major pharmaceutical companies have employed grid computing to expand their compute resources with the intention of minimizing additional financial expenditure. Historically, one of the issues restricting widespread utilization of the grid resources in molecular modeling is the limited set of suitable applications amenable to coarse-grained parallelization. Recent advances in grid infrastructure technology coupled with advances in application research and redesign will enable fine-grained parallel problems, such as quantum mechanics and molecular dynamics, which were previously inaccessible to the grid environment. This will enable new science as well as increase resource flexibility to load balance and schedule existing workloads. PMID:18598912

CORNEAL ANGIOGENIC PRIVILEGE: ANGIOGENIC AND ANTIANGIOGENIC FACTORS IN CORNEAL AVASCULARITY, VASCULOGENESIS, AND WOUND HEALING (AN AMERICAN OPHTHALMOLOGICAL SOCIETY THESIS)  

PubMed Central

Purpose To determine the molecular basis of corneal avascularity during wound healing and determine the role of angiogenic and antiangiogenic factors in corneal vasculogenesis. Methods The expression of proangiogenic factors (vascular endothelial growth factor [VEGF]; basic fibroblast growth factor [bFGF]; matrix metalloproteinase-2 [MMP-2]; and membrane-type 1-MMP [MT1-MMP]) and antiangiogenic factors (pigment epithelium–derived factor [PEDF]; angiostatin; restin; and endostatin) was analyzed in avascular corneas and in models of corneal neovascularization (bFGF pellet implantation, intrastromal injection of MT1-MMP cDNA, and surgically induced partial limbal deficiency). Results Immunohistochemistry demonstrated the presence of antiangiogenic factors (PEDF, angiostatin, restin, and endostatin) and proangiogenic molecules (VEGF, bFGF, MMP-2, and MT1-MMP) in the cornea after wounding. Proangiogenic MMPs were upregulated in stromal fibroblasts in the vicinity of invading vessels following bFGF pellet implantation. Corneal neovascularization (NV) was also induced by intrastromal injection of MT1-MMP naked cDNA in conjunction with de-epithelialization. Partial limbal deficiency (HLD-) resulted in corneal NV in MMP-7 and MMP-3 knockout mice but not in wild type controls. Conclusions Corneal angiogenic privilege is an active process involving the production of antiangiogenic factors to counterbalance the proangiogenic factors (which are upregulated after wound healing even in the absence of new vessels). Our finding that the potent antiangiogenic factors, angiostatin and endostatin, are colocalized with several MMPs during wound healing suggests that MMPs may be involved in the elaboration of these antiangiogenic molecules by proteolytic processing of substrates within the cornea.

Uropathogenic E. coli induce different immune response in testicular and peritoneal macrophages: implications for testicular immune privilege.  

PubMed

Infertility affects one in seven couples and ascending bacterial infections of the male genitourinary tract by Escherichia coli are an important cause of male factor infertility. Thus understanding mechanisms by which immunocompetent cells such as testicular macrophages (TM) respond to infection and how bacterial pathogens manipulate defense pathways is of importance. Whole genome expression profiling of TM and peritoneal macrophages (PM) infected with uropathogenic E. coli (UPEC) revealed major differences in regulated genes. However, a multitude of genes implicated in calcium signaling pathways was a common feature which indicated a role of calcium-dependent nuclear factor of activated T cells (NFAT) signaling. UPEC-dependent NFAT activation was confirmed in both cultured TM and in TM in an in vivo UPEC infectious rat orchitis model. Elevated expression of NFATC2-regulated anti-inflammatory cytokines was found in TM (IL-4, IL-13) and PM (IL-3, IL-4, IL-13). NFATC2 is activated by rapid influx of calcium, an activity delineated to the pore forming toxin alpha-hemolysin by bacterial mutant analysis. Alpha-hemolysin suppressed IL-6 and TNF-? cytokine release from PM and caused differential activation of MAP kinase and AP-1 signaling pathways in TM and PM leading to reciprocal expression of key pro-inflammatory cytokines in PM (IL-1?, IL-1?, IL-6 downregulated) and TM (IL-1?, IL-6 upregulated). In addition, unlike PM, LPS-treated TM were refractory to NF?B activation shown by the absence of degradation of I?B? and lack of pro-inflammatory cytokine secretion (IL-6, TNF-?). Taken together, these results suggest a mechanism to the conundrum by which TM initiate immune responses to bacteria, while maintaining testicular immune privilege with its ability to tolerate neo-autoantigens expressed on developing spermatogenic cells.
